Patent ID: 8009244

Claim:
A liquid crystal display device, comprising: a liquid crystal display panel formed by enclosing a liquid crystal layer between a pair of transparent substrates having a pixel-forming electrode on an inner surface; and a backlight for irradiating an illumination light on the liquid crystal display panel, wherein the backlight includes: a plurality of light-emitting elements; a circuit board on which the plurality of light-emitting elements are disposed; an optical guide facing the plurality of light-emitting elements, wherein each of the plurality of light-emitting elements is disposed on the circuit board at a predetermined interval from each other; wherein the optical guide includes a main surface disposed opposite to liquid crystal display panel and a side surface; wherein the plurality of light-emitting elements disposed opposite to the side surface of the optical guide: a case for housing the circuit board and the optical guide; and a spacer which prevents the optical guide from coming in contact with the plurality of light-emitting elements, said spacer being disposed between the optical guide and the circuit board, wherein the spacer is disposed between at least two of the plurality of light-emitting elements; wherein the case includes: a flat part on which the optical guide is mounted; a side wall standing substantially perpendicular to the flat part which supports the circuit board; and a depression, which is disposed between this side wall and the flat part, the depression housing the lower part of the circuit board and being set back substantially parallel to the side wall from the edge of the flat part, the depression opens up in a direction perpendicular to a direction of the side surface of the optical guide.
