Patent ID: 8144382

Claim:
An image display device comprising a first substrate, a second substrate which faces the first substrate, and a plurality of pixels, wherein a first insulation layer and first electrodes which are disposed under the first insulation layer are formed on the first substrate, a second insulation layer and second electrodes which are disposed under the second insulation layer are formed on the second substrate, each of the pixels has one of the first electrodes, one of the second electrodes, and an area which is surrounded by the first insulation layer, the second insulation layer, and partition walls each having a conductive layer, a first oil layer and a second oil layer include oil of a nonpolar material, and are formed in the area, the first oil layer is disposed at a side of the first insulation layer, the second oil layer is disposed at a side of the second insulation layer, an ON voltage or an OFF voltage is applied to the first electrode and the second electrode, the first insulation layer has a first region which overlaps the first electrode and a second region which does not overlap the first electrode as viewed in a direction from the display screen, the second insulation layer has a third region which overlaps the second electrode and a fourth region which does not overlap the second electrode as viewed in a direction from the display screen, and the second region and the fourth region of each of the pixels do not overlap each other as viewed in a direction from the display screen.
