A surface light source device includes a light guiding plate which is transparent, a line light source provided on one end edge of the light guiding plate, an end edge reflection layer provided on the other end edge of the light guiding plate, and a light diffusion/transmission section provided on a back face of the light guiding plate. A ratio of an area of the light diffusion/transmission section to a whole area of the back face of the light guiding plate gradually increases with an increase in distance from the light source end edge in a region from the end edge on the light source end of the light guiding plate to a position at which a surface emission luminance of the light guiding plate is lowest, and is constant in a region from the position to the other end edge on the end edge reflection layer end of the light guiding plate. A back face reflection layer which is white is provided on the back face of the light guiding plate.

摘要:
A liquid crystal display device includes a liquid crystal display panel and a parallax barrier with a barrier light-shielding layer patterned on a barrier glass, bonded with an adhesive layer composed of an ultraviolet curing resin, provided with an area without a light-shielding layer on the peripheral portion of the parallax barrier, and a sealing material is arranged between a TFT substrate and a CF substrate with at least a portion thereof overlapping with the area without the light-shielding layer. Thus, peeling on the bonding surfaces between the parallax barrier and the liquid crystal display panel does not easily occur, and the occurrence of display non-uniformity due to strain of the CF substrate is prevented.
