Display apparatus and method for manufacturing same

Abstract

A display apparatus includes a window member, a display module, and a photocured adhesive layer. The window member includes a base member and a bezel layer overlapping a partial region of a rear surface of the base member, the bezel layer including a photosensitive material having a reduced transmittance with an increased amount of irradiated light. The display module is disposed on the lower side of the window module. The photocured adhesive layer is configured to bind the window member to the display module, and overlaps with the bezel layer on a plane.

What is claimed is: 
     
         1 . A display apparatus, comprising:
 a window member comprising a base member and a photocured bezel layer overlapping a partial region of a rear surface of the base member, wherein the photocured bezel layer comprises a photocured photosensitive material having a reduced transmittance with an increased amount of irradiated light;   a display module disposed on a lower side of the window member; and   a photocured adhesive layer overlapping the photocured bezel layer on a plane and configured to bind the base member and the display module.   
     
     
         2 . The display apparatus of  claim 1 , wherein the photosensitive material comprises at least one of a spiro-naphtho-oxazine compound, a spiro-anthra-oxazine compound, or a spiropyran-based compound. 
     
     
         3 . The display apparatus of  claim 1 , wherein the photosensitive material comprises at least one of 1,3-dihydro-1,3,3-trimethylspiro[2H-indole-2,3′-[3H]naphth[2,1-b][1,4]oxazine], 1,3-dihydro-1,3,3-trimethylspiro[2H-indole-2,3′-[3H]phenanthr[9,10-b](1,4)oxazine], or trinitro fluorenone. 
     
     
         4 . The display apparatus of  claim 1 , comprising an opening through which an image is transmitted, wherein the opening is on a front surface of the window member and defined in the bezel layer. 
     
     
         5 . The display apparatus of  claim 4 , wherein the display module comprises:
 a display member configured to produce the image; and   a touch member configured to sense an external input.   
     
     
         6 . The display apparatus of  claim 5 , wherein the touch member comprises:
 a plurality of touch sensors; and   a plurality of signal lines coupled to the plurality of touch sensors and overlapping the bezel layer.   
     
     
         7 . The display apparatus of  claim 1 , wherein, on the front face of the window member, the photocured bezel layer comprises:
 a first part and a second part opposite each other in a first direction; and   a third part and a fourth part opposite each other in a second direction which crosses the first direction.   
     
     
         8 . The display apparatus of  claim 7 , wherein the third part is configured to couple an end of the first part to an end of the second part, and the fourth part is configured to couple another end of the first part to another end of the second part. 
     
     
         9 . The display apparatus of  claim 1 , further comprising a protecting cover configured to protect the display module. 
     
     
         10 . A method of manufacturing a display apparatus, comprising:
 providing a light-transmittable, photocurable preliminary bezel layer on a surface of a base member, wherein the preliminary bezel layer overlaps a partial region of the base member and comprises a photosensitive material;   providing a photocurable preliminary adhesive layer on a surface of a display module or on the surface of the base member;   contacting the base member and the display module such that the photocurable preliminary adhesive layer overlap the preliminary bezel layer and the photocurable preliminary adhesive layer is disposed between the surface of the base member and the surface of the display module; and   irradiating light on a surface of the preliminary bezel layer which is opposite to the surface of the base member such that the preliminary bezel layer is cured to form a bezel layer having a predetermined transmittance.   
     
     
         11 . The method of  claim 10 , wherein during the irradiating of light on the preliminary bezel layer the light is simultaneously irradiated on the photocurable preliminary adhesive layer. 
     
     
         12 . The method of  claim 10 , wherein the photosensitive material comprises at least one of a spiro-naphtho-oxazine compound, a spiro-anthra-oxazine compound, and a spiropyran-based compound. 
     
     
         13 . The method of  claim 10 , wherein the photosensitive material comprises at least one of 1,3-dihydro-1,3,3-trimethylspiro[2H-indole-2,3′-[3H]naphth[2,1-b][1,4]oxazine], 1,3-dihydro-1,3,3-trimethylspiro[2H-indole-2,3′-[3H]phenanthr[9,10-b](1,4)oxazine], or trinitro fluorenone. 
     
     
         14 . The method of  claim 10 , further comprising binding a protecting cover to the base member or the display module. 
     
     
         15 . The method of  claim 10 , wherein the preliminary bezel layer has a line shape disposed along the perimeter of the surface of the base member. 
     
     
         16 . The method of  claim 10 , wherein the display module comprises:
 a display member configured to produce an image; and   a touch member configured to sense external input.
