Abstract:
A liquid crystal display device includes a device substrate that includes a pixel electrode, a counter substrate that is formed opposite the device substrate and that includes a counter electrode, a liquid crystal layer that is formed between the device substrate and the counter substrate, a first alignment layer that is formed on a side of the device substrate which is closer to the liquid crystal layer, and a second alignment layer that is formed on a side of the counter substrate which is closer to the liquid crystal layer. The pixel electrode is made of a material having a work function smaller than that of a material for the counter electrode. The first alignment layer has substantially the same density as that of the second alignment layer, and the thickness d1 of the first alignment layer is greater than the thickness d2 of the second alignment layer.
