Patent ID: 8330909

Claim:
A liquid crystal display device including: a plurality of dot regions in each of which a color filter layer is provided; and a transmissive region included in each of the dot regions, for causing information to be displayed by causing light emitted from a light source to be transmitted through the transmissive region, a reflective region defined by a reflective electrode and included in each of the dot regions, for causing information to be displayed by causing light to be reflected in the reflective region, so that each of the plurality of dot regions includes a transmissive region and a reflective region; wherein the color filter layer has a first region in the transmissive region, the first region being a region whose transmittance is higher than a transmittance of a color layer; and a light detection element provided in part of the transmissive region, for detecting an intensity of light which enters the light detection element, the light directly entering the light detection element through the first region.
