Abstract
The present invention provides a liquid crystal display device which can largely suppress the reduction of contrast which occurs in a light reflection mode of a liquid crystal display device. On a liquid-crystal-side surface of one of substrates which are arranged to face each other in an opposed manner while sandwiching liquid crystal therebetween, the liquid crystal display device includes pixel regions each of which is classified into a light reflection portion and a light transmission portion. On each pixel region, a first light-transmitting pixel electrode which is formed on the light reflection portion and the light transmission portion, a material layer which is formed on a major portion of the light reflection portion, an insulation layer having an opening formed at a portion corresponding to the light transmission portion, and a second pixel electrode which is formed on the light reflection portion and functions as a reflection film are sequentially laminated.
