LIQUID CRYSTAL DISPLAY DEVICE Russian patent published in 2014 - IPC G02F1/13357 

FIELD: physics.

SUBSTANCE: liquid crystal display device (100) of the present invention includes a liquid crystal display panel (10) and a lateral illumination unit (20) which emits light from a position which is lateral with respect to the panel (10). The panel (10) includes a front substrate (1), a back substrate (2) and a light-diffusing liquid crystal layer (3). The unit (20) includes a light source (7), which is situated in a position which is lateral with respect to the panel (10), and a light-guide (6), having a light-output surface (6b) through which light emitted by the light source (7) as well as light incident on the light-guide (6) is emitted towards the end surface (1a) of the substrate (1). The surface (6b) is slanted relative a direction which is vertical with respect to the front surface (1b) of the substrate (1), such that it faces the back surface of the panel (10).

EFFECT: preventing generation of a bright line in the panel.
