Abstract
Provided is a liquid crystal display device capable of providing bright display with low voltage applied during both reflective display and transmissive display, and achieving a wide color gamut. The liquid crystal display device, includes: a liquid crystal panel including a first substrate, a second substrate, and a liquid crystal layer. The pixels each include a reflective region and a transmissive region. The first substrate includes, in order toward the liquid crystal layer, a first color filter layer, a reflective electrode, a transparent insulating layer, and pixel electrodes. The reflective electrode is disposed in the reflective region and has an aperture in the transmissive region. The pixel electrodes are in the respective pixels, each being in the reflective region and the transmissive region in the corresponding pixel. The second substrate includes a second color filter layer and a counter electrode.
