Liquid crystal display device

A liquid crystal display device comprising:

• a light source;
• a light guide body which guides light from the light source;
• a main liquid crystal display panel which is arranged on one surface side of the light guide body;
• and
• a sub liquid crystal display panel which is arranged on another surface side of the light guide body and is smaller than the main liquid crystal display panel, wherein
• the liquid crystal display device includes a holding portion which has a first side which holds the main liquid crystal display panel and the light guide body and a second side which holds the sub liquid crystal display panel,
• the holding portion has an opening portion between the light guide plate arranged on the first side and the sub liquid crystal display panel arranged on the second side,
• an optical sheet is arranged on the first side of the holding portion corresponding to a position where the sub liquid crystal display panel is arranged, and
• the reflectance wavelength characteristic of a bottom surface of the first side of the holding portion is substantially equal to the reflectance wavelength characteristic of the optical sheet which is arranged corresponding to the sub liquid crystal display panel.

A liquid crystal display device comprising:

• a casing having a first recessed portion which opens on one side and a second recessed portion which opens on another side opposite to said one side, wherein the second recessed portion has a bottom surface thereof opened on the first recessed portion side,
• a main liquid crystal display panel which is housed in the first recessed portion of the casing;
• and
• a sub liquid crystal display panel which is housed in the second recessed portion of the casing, wherein
• the reflectance wavelength characteristic of the bottom surface of the first recessed portion is substantially equal to the reflectance wavelength characteristic of the sub liquid crystal display panel as measured from the first recessed portion side.
