Display device and manufacturing method thereof

Abstract

Simple and high-precision processing, and narrowing of the frame are to be facilitated at the time of preparing display panels by multiple formation. After bonding a first substrate layer in which a plurality of element substrates is formed on a support plate and a second substrate layer in which a plurality of counter substrates is formed on a support plate, these substrate layers are divided into a plurality of display panels. Ridge-like ribs of a covalently or ionically bonding inorganic material are formed along edges of the element substrate and the counter substrate. The dividing includes scribing the support plates along the ribs, and flexing and breaking the support plates.

1 . A display device comprising:
 a support plate;   an element substrate including a multilayer structure having a resin film, the multilayer structure having a display area where a display element is formed; and   a rib surrounding the multilayer structure, wherein   the rib is in contact with an outer peripheral lateral surface of the element substrate, and   the outer peripheral lateral surface of the rib and an outer peripheral lateral surface of the support plate are coplanar on a plane that is perpendicular to the multilayer structure.   
     
     
         2 . The display device according to  claim 1 , further comprising a cover layer which covers the display area, wherein
 the cover layer continuously extends from a region above the element substrate to a region above the rib.   
     
     
         3 . The display device according to  claim 1 , wherein
 the rib includes an inorganic oxide or inorganic nitride.   
     
     
         4 . The display device according to  claim 1 , further comprising a filler covering the display area, wherein
 the filler is at an area where is surrounded by the rib.
