Abstract:
1. A liquid crystal display device, comprising: a thin backlight system, including: the light deflection system including: said liquid crystal display device, further including: a liquid crystal element including: a liquid crystal layer in which picture elements serving as the plurality of light transmitting portions are arranged; a first glass substrate provided on a first side from which a light is received; and a second glass substrate provided on a second side from which the light is emitted, the liquid crystal layer being sandwiched between the first glass substrate and the second glass substrate; a drive element configured to drive the liquid crystal element; a polarizer provided on the first glass substrate; and an analyzer provided on the second glass substrate; wherein the imaging optical system includes a fly-eye lens, the irradiating optical system includes a total reflection Fresnel sheet, the fly-eye lens is provided between the polarizer and the first glass substrate and in contact with the polarizer and the first glass substrate, the fly-eye lens includes (i) a convex surface on a side which faces the irradiating optical system and (ii) a flat surface on a side which faces the plurality of light transmitting portions, and the total reflection Fresnel sheet includes a flat surface which contacts a surface of the polarizer through which the lights enter.
