Abstract
A liquid crystal display device which efficiently introduces radiation light of light-emitting elements to a light guide body to thereby obtain a uniformly bright display screen. The liquid crystal display device includes a liquid crystal display panel, a light guide body installed at a back face of the liquid crystal display panel, a light-emitting element disposed proximate to a side wall of the light guide body, and a mold case having an elastic support structure which hold the light guide body and biases the light guide body toward the light-emitting element.
