  • Liquid crystal display device with a display surface of a planar shape
    Patent number: 11131876
    Abstract: In a liquid crystal display device, the liquid crystal panel has a display surface of a planar shape on which a plurality of pixels are located. The front protective plate is located so as to face the display surface of the liquid crystal panel. The optical path changing portion is located between an emission surface of the front protective plate and an air layer located closer to the back side than the emission surface is and located closest to the emission surface. The optical path changing portion changes an optical path of light that enters the optical path changing portion so as to expand an emission angle when the incident light is emitted from the emission surface of the front protective plate.
