Electronic apparatus

Abstract

An electronic apparatus includes a back light unit that has a light source, an optical member that is arranged so as to face the irradiation direction of the light of the light source, and a spacer that supports the optical member from the light source side and is arranged in a state in which the optical member is arranged parallel to the direction of gravity or inclined with respect to the direction of gravity, and a display panel that is arranged so as to be superimposed on the optical member of the back light unit. In the back light unit, the number of spacers arranged in an upper half area of the optical member with respect to the direction of gravity is configured to be smaller than that of the spacers arranged in a lower half area of the optical member with respect to the direction of gravity.

1 . An electronic apparatus comprising:
 a back light unit that includes a light source, an optical member having a flat shape that is arranged so as to face the irradiation direction of the light of the light source, and a spacer that supports the optical member from the light source side and is arranged in a state in which a face of the optical member is arranged parallel to the direction of gravity or inclined with respect to the direction of gravity; and   a display panel that is arranged so as to be superimposed on a face through which light is emitted from the optical member of the back light unit,   wherein, in the back light unit, the number of spacers arranged in an upper half area of the face of the optical member with respect to the direction of gravity is configured to be smaller than that of the spacers arranged in a lower half area of the face of the optical member with respect to the direction of gravity.   
     
     
         2 . The electronic apparatus according to  claim 1 , wherein the back light unit arranges at least one spacer in the lower half area of the optical member. 
     
     
         3 . The electronic apparatus according to  claim 1 , wherein, in the back light unit, the spacers arranged in the lower half area of the optical member are arranged in positions in which the flexural amount of the lower half area of the optical member is increased. 
     
     
         4 . The electronic apparatus according to  claim 1 , further comprising a support mechanism that supports the electronic apparatus,
 wherein the support mechanism includes a support post that arranges the back light unit to be parallel to the direction of gravity or to be inclined with respect to the direction of gravity.   
     
     
         5 . The electronic apparatus according to  claim 4 , wherein the support mechanism further includes a rotation mechanism that freely rotates the back light unit to a reference position and in at least one direction between the clockwise direction and the counterclockwise direction from the reference position. 
     
     
         6 . An electronic apparatus comprising:
 a back light unit that includes a light source, an optical member having a flat shape that is arranged so as to face the irradiation direction of the light of the light source, and a spacer that supports the optical member from the light source side and is arranged in a state in which a face of the optical member is arranged parallel to the direction of gravity or inclined with respect to the direction of gravity; and   a display panel that is arranged so as to be superimposed on a face through which light is emitted from the optical member of the back light unit,   wherein the back light unit is formed so as to be freely rotatable to a reference position and at least one direction between a clockwise direction and a counterclockwise direction from the reference position, and, in any of the reference positions, a position rotated in the clockwise direction, and a position rotated in the counterclockwise direction, the number of the spacers arranged in an upper half area of the face of the optical member with respect to the direction of gravity is configured to be smaller than that of the spacers arranged in a lower half area of the face of the optical member with respect to the direction of gravity.   
     
     
         7 . The electronic apparatus according to  claim 6 , wherein, in the back light unit, the spacers arranged in the lower half area of the optical member are arranged in positions in which the flexural amount of the lower half area of the optical member is increased. 
     
     
         8 . The electronic apparatus according to  claim 6 , further comprising a support mechanism that supports the electronic apparatus,
 wherein the support mechanism includes a support post that arranges the back light unit to be parallel to the direction of gravity or to be inclined with respect to the direction of gravity.   
     
     
         9 . The electronic apparatus according to  claim 8 , wherein the support mechanism further includes a rotation mechanism that freely rotates the back light unit to a reference position and in at least one direction between the clockwise direction and the counterclockwise direction from the reference position.
