Patent ID: 7262754

Claim:
An electronic device comprising: a reflection type liquid crystal panel comprising an active matrix substrate, a counter substrate, a liquid crystal interposed between the active matrix substrate and the counter substrate, and a color filter adjacent to the counter substrate, wherein said active matrix substrate has a plurality of thin film transistors and a plurality of pixel electrodes connected with the thin film transistors; a light source comprising 3-color light emitting diodes for producing three primary colors for additive color mixing; and a reflection plate located adjacent to the liquid crystal panel with the light emitting diodes interposed therebetween, said light emitting diodes and the reflection plate arranged horizontally with respect to the liquid crystal panel, wherein white light emitted from the light source is introduced into said liquid crystal panel from sides of said counter substrate of said liquid crystal panel, wherein at least a part of the white light introduced to said counter substrate is reflected on the interface between the liquid crystal and the pixel electrode so as not to pass through the active matrix substrate.
