Abstract
Official abstract text for this publication.
A liquid crystal display device includes a plurality of light source packages each having a light-emitting portion for emitting light, a light guide plate which light emitted from the light source packages enters through the incidence surface, having a height and a width, and from which the light exits through the exit surface, and a liquid crystal display panel for controlling, for each pixel, the orientation of a liquid crystal material to control the transmission of the light exiting through the exit surface. Each light source package has two opposing long sides and two opposing short sides when viewed from the direction of the light emitted by the light-emitting portion. The plurality of light source packages are arranged long side to long side in the direction along the width.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid crystal display device comprising: a plurality of light source packages each having a light-emitting portion for emitting light; a light guide plate including an incidence surface which faces the light-emitting portion, the incidence surface having a height and a width, the light guide plate including an exit surface, light emitted from the light-emitting portion being incident on the incidence surface and exiting through the exit surface; and a…
