LIQUID CRYSTAL DISPLAY APPARATUS AND BACKLIGHT
First Claim
1. A liquid crystal display device having a plurality of pixels arranged in a matrix along a first direction and a second direction which are perpendicular to each other, comprising:
- a TFT substrate including a plurality of pixel electrodes arranged so as to correspond to the plurality of pixels;
a counter substrate including a counter electrode which opposes to the pixel electrodes;
a liquid crystal layer interposed between the TFT substrate and the counter substrate;
an optical film including a polarizer provided on a surface of the TFT substrate which is opposite to the liquid crystal layer; and
a backlight provided on a side of the optical film which is opposite to the TFT substrate,wherein the backlight includes a light guide plate for guiding light emitted from a light source and an optical element layer provided on a side of the light guide plate which is closer to the optical film, andthe optical element layer includes a plurality of lenticular lenses extending in the first direction, each of the lenticular lenses having a light receiving surface protruding toward the light guide plate.
