Abstract
A liquid crystal display device includes a first substrate, a second substrate, and a liquid crystal layer. Each pixel includes a reflective region and a transmissive region. The first substrate includes a reflective layer, an interlayer insulating layer provided to cover the reflective layer, and a pixel electrode provided on the interlayer insulating layer in each pixel. The interlayer insulating layer has a recess portion which is defined by a bottom surface and an inclined side surface and at least a part of which is located in the transmissive region. A depth of the recess portion of the interlayer insulating layer is 0.5 μm or more, and an inclination angle of the inclined side surface of the recess portion is 25° or less.
