Abstract
A liquid crystal display device which includes a pair of substrates, a pixel including a liquid crystal element between the pair of substrates, a lighting portion provided on the outer side of the pair of substrates, a first polarizing member between the pair of substrates and the lighting portion, a reflective member provided outside the lightning portion, a second polarizing member on a side opposite to the first polarizing member with the pair of substrates provided therebetween, and a first optical sensor and a second optical sensor. The first optical sensor has a function of detecting illuminance of external light, and the second optical sensor has a function of detecting a color tone of polarized light emitted from the pixel portion. The lightning portion can emits light having a predetermined wavelength depending on the color tone of the pixel portion which is detected by the second optical sensor.
