Abstract: An optical member is disposed between an optical sheet and a pair of middle chassis and top chassis that securely support an edge of an liquid crystal panel and an edge of the optical sheet. The optical member reflects light emitted from light-emitting diodes at high reflectivity so that an amount of light loss through the edge of the optical sheet is reduced. This allows for higher light utilization efficiency, thereby enhancing the brightness.

The black insulating layers provide a black mask between the phosphor layers to improve the contrast ratio, and the conductive layers are effective to increase the percentage of electron beam utilization, thus improving the quality and resolution of displayed images. These advantages can be achieved without making image display unstable due to charging-up of the black mask and straying of secondary electrons.
