Patent ID: 6866393

Claim:
A reflective liquid crystal display comprising: a plane light source device having (a) a light pipe including an incident side, an upper surface, and a lower surface, one of the upper and the lower surfaces having light emitting means for emitting light incident on the incident side from the other one of the upper and the lower surfaces, which constitutes a light emitting side of the plane light source device, and (b) a light source arranged on the incident side of said light pipe; and a liquid crystal display panel having a reflective layer and a visual recognition side facing said plane light source device; wherein the light emitting side of said plane light source device and the visual recognition side of said liquid crystal display panel are bonded to each other through an adhesive layer, such that no air layer is interposed between said plane light source device and said liquid crystal display panel, and wherein said adhesive layer has a refractive index that is lower than refractive index of said light pipe.
