Abstract: A liquid crystal display device includes a liquid crystal display panel and a backlight device. The backlight device includes: a light guide for emitting a planar light beam, a first optical sheet disposed on a back side of the light guide, and an optical sheet group disposed on an irradiation-surface side of the light guide and including a plurality of optical sheets arranged in stacked relation. Periphery parts of the first optical sheet and at least one second optical sheet of the optical sheet group are bonded together to form a bag shape, and the light guide and the other optical sheets are retained in the bag-like body formed of the first optical sheet and the second optical sheet.

Abstract: A parallax barrier panel includes plural sub-areas which are arranged in an X direction, plural light-shielding area each of which includes the plural sub-areas in a light-shielding state, and plural light-transmitting areas each of which includes the plural sub-areas in a light-transmitting state and which are arranged alternately with the plural light-shielding areas in the X direction. The sub-areas extend in a Y direction and can be switched between the light-transmitting state and the light-shielding state. Each of the sub-areas is provided with an electrode for controlling a liquid crystal layer. A first electric line is connected to an upper end part of the electrode, and a second electric line is connected to a lower end part of the electrode.
