ABSTRACT:
A liquid crystal display device includes a first substrate, a second substrate, and a liquid crystal layer interposed between the first substrate and the second substrate, the liquid crystal display device having a dot region as an image display unit, the dot region including a transmissive display region and a reflective display region, wherein a thickness adjustment layer for adjusting the thickness of the liquid crystal layer is disposed between the liquid crystal layer and at least one of the first substrate and the second substrate, the thickness adjustment layer decreasing the thickness of the liquid crystal layer in the reflective display region compared with the thickness of the liquid crystal layer in the transmissive display region, and a metal line is placed on the second substrate so as to overlap, in plan view, an inclined region of the thickness adjustment layer disposed between the transmissive display region and the reflective display region.
