Liquid crystal display device and electronic device

A liquid crystal display device including:

• 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,
• the liquid crystal display device comprising:
• a first region provided on the color filter layer 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 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.
