[0088] Figure 13 is a cross-sectional view of the liquid crystal display device of the second embodiment, Figure 14 It is a longitudinal sectional view of the liquid crystal display device of the second embodiment.
[0089] Such as Figure 13 and Figure 14 As shown, according to the present embodiment, in the liquid crystal display device 10, the optical sheet OS of the backlight unit 20 is adhered to the second surface SF2 of the frame 16 via the second diffusion adhesive layer 24b. The optical sheet OS faces the light guide plate LG with a gap. The optical sheet OS includes a diffusion sheet OS1 adhered to the upper surface SF2 of the frame 16 via a second diffusion adhesive layer 24b, and a prism sheet OS2 arranged to overlap the diffusion sheet OS1. In addition, prism sheet OS2 is in contact with polarizing plate PL2 of liquid crystal display panel 12 , that is, is in surface contact with the entire surface of polarizing plate PL2 . In addition, the polarizing plat...
