Liquid crystal display device

A liquid crystal display device comprising:

• a first substrate comprising:
• a transparent sheet-like first electrode formed of a transparent conductive film;
• a first insulator formed to overlie an upper surface of the sheet-like first electrode;
• a plurality of transparent linear second electrodes formed by a transparent conductive film on the first insulator so as to at least overlie the first insulator and the sheet-like first electrode;
• a second insulator formed on the first insulator so as to overlie the plurality of linear second electrodes, the first insulator and the sheet-like first electrode;
• an alignment film formed on the second insulator;
• and
• a second substrate;
• wherein the first substrate and the second substrate interpose liquid crystal therebetween and arranged to be opposed to each other, the liquid crystal being in contact with the alignment film formed on the second insulator, wherein the sheet-like first electrode, the first insulator, and the plurality of linear second electrodes are provided in a pixel region on a surface of the first substrate of a side of the liquid crystal,
• wherein the liquid crystal display device is driven by rotating liquid crystal molecules in a plane parallel to the first substrate by a voltage applied between the sheet-like first electrode and the plurality of linear second electrodes,
• wherein the second insulator is made of the same material as the first insulator,
• wherein the second insulator has a thickness which is less than a thickness of the first insulator,
• wherein the thickness of the second insulator enables suppression of charge injection and prevention of image sticking, and
• wherein the second insulator is formed between the alignment layer and the plurality of linear second electrodes including in an area in which an opening is formed and extends in a layer lower than a layer of the sheet-like first electrode.
