Abstract
A backlight for a color liquid crystal display apparatus includes a first light-guide plate; a first incidence part for receiving light of a first primary color in a first area on a first lateral surface of the first light-guide plate; a second incidence part for receiving light of a second primary color light in a second area on a second lateral surface that is opposite to the first lateral surface of the first light-guide plate; and a third incidence part for receiving light of a third primary color in a third area on a rear surface of the first light-guide plate. The number of superposition steps is thereby reduced, light-guide plates can easily be superposed onto an LCD panel with high accuracy, and a lightweight and inexpensive backlight for a color liquid crystal display apparatus can be obtained.
