A backlight for a color liquid crystal display apparatus in which light of the three primary colors of red, blue, and green is directly incident on the corresponding pixels of a liquid crystal layer, the backlight comprising a first light-guide plate; a first incidence part for receiving light of a first primary color from among the light of the three primary colors 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 from among the light of the three primary colors 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 from among the light of the three primary colors 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.
