Liquid crystal display device
View Patent ↗In a liquid crystal display device, a recessed portion is formed in a portion of a periphery of a lower frame, a columnar member is provided to the recessed portion, the columnar member is allowed to pass through a hole formed in a projecting portion which is provided on an optical sheet, and a side surface of a liquid crystal panel is brought into contact with the columnar member. The columnar member provided on the lower frame not only determines the position of the liquid crystal panel with respect to the lower frame, but also determines the position of the optical sheet with respect to the lower frame and firmly holds the optical sheet onto the lower frame, thus preventing the disengagement of the optical sheet from the lower frame.
1. A display device comprising:
a liquid crystal panel;
a light diffusion sheet; and
a case formed by resin molding,
wherein:
the diffusion sheet is disposed between the liquid crystal panel and the case, and comprises a first side, and a second side which is opposing to the first side, and a third side which is transverse to the first side and the second side, and a fourth side which is opposing to the third side
a length of the first side is longer than a length of the third side, and the first side is an upper side and the second side is a lower side,
a first oblong shape through hole and a second oblong shape through hole are formed on the first side, and the both through holes are disposed between the first side and the second side,
the case comprises a first columnar member and a second columnar member passing through the first oblong shape through hole and the second oblong shape through hole, and
the first columnar member and the second columnar member serves as a guide for positioning the liquid crystal panel.
2. A display device according to claim 1 , wherein the first oblong shape through hole is disposed adjacent to the third side, and the second oblong shape through hole is disposed to the fourth side.
3. A display device according to claim 1 , wherein the diffusion sheet further comprises a circular shape through hole, and the case comprises a third columnar member passing through the circular shape through hole for positioning the diffusion sheet.
4. A display device according to claim 3 , wherein the diffusion sheet comprises a projection portion, and the circular shape through hole is formed the projection portion.
