Patent ID: 8279164

Claim:
A liquid crystal display apparatus comprising: a liquid crystal display panel in which a plurality of pixels are arranged in a matrix form; a light guide plate including an exit surface facing the liquid crystal display panel, a flat light incidence facet, and an opposite surface opposite from the exit surface, wherein the light guide plate guides light incident from the flat light incidence facet to the exit surface via the opposite surface, wherein the opposite surface comprises a reflecting pattern which reflects the incident light toward the exit surface such that an angle of a peak intensity of exit light emitted from the exit surface varies according to a light incident position on the flat light incidence facet; a first light-emitting element configured to emit first light onto said flat light incidence facet so that the exit light emitted from the exit surface has a first peak intensity that is at angle perpendicular to the exit surface; a second light-emitting element configured to emit second light onto said flat light incidence facet so that the exit light emitted from the exit surface has a second peak intensity that is at an angle inclined only to a first direction from perpendicular to the exit surface; a first memory for storing display image data which are successively supplied from an outside; a second memory for storing predetermined fixed image data or the display image data successively supplied from the outside; a display control section for causing the liquid crystal display panel to perform display based alternately on the image data stored in the first memory and the image data stored in the second memory, at a predetermined timing; and a light source control section for controlling the first and second light-emitting elements to alternately emit the first and second lights in synchronization with the predetermined timing, wherein the reflecting pattern includes a plurality of arc-like inclined surfaces which do not cross each other and which have a common central position at a first position, which is a central position of the flat light incidence facet; and wherein the first light-emitting element is arranged to face the first position, and the second light-emitting element is positioned to face a second position of the flat light incidence facet that is apart from the first position.
