Abstract: A liquid crystal display device includes a first substrate; a second substrate; and a vertical alignment-type liquid crystal layer. The first substrate includes a backplane circuit, a first interlayer insulating layer covering the backplane circuit, a first reflective electrode provided on the first interlayer insulating layer and including a first region located in each of pixels and a second region located between any two adjacent pixels, a second interlayer insulating layer covering the first reflective electrode, and a pixel electrode provided on the second interlayer insulating layer in each pixel. The pixel electrode is electrically connected with the backplane circuit in first and second contact holes formed in the first and second interlayer insulating layers. The first substrate further includes a second reflective electrode provided on the second interlayer insulating layer so as to overlap the first contact hole as seen in a direction normal to a display surface.
