Patent ID: 7483110

Claim:
A liquid crystal display device comprising: a first substrate; a second substrate; a liquid crystal layer and a seal arranged between the first substrate and the second substrate; a display region; and a non-display region surrounding the display region, the non-display region including a liquid crystal layer region having the liquid crystal layer arranged therein and a sealed region having the seal arranged therein; wherein the first substrate includes a thin-film transistor, an insulating resin film, and a pixel electrode, arranged in this order, extending toward the liquid crystal layer, and further includes a first dummy electrode in the liquid crystal layer region of the non-display region; the pixel electrode is connected to a drain electrode of the thin-film transistor through a contact hole formed in the insulating resin film; the second substrate includes a transparent common electrode above a color filter and a black mask, and includes a second dummy electrode in the liquid crystal layer region of the non-display region; the first dummy electrode is arranged to be separated from the pixel electrode of a display region, and the first dummy electrode and the pixel electrode are formed of the same material; the second dummy electrode extends from the common electrode of the display region; and the first and second dummy electrodes each encircle the display region and have substantially the same potential.
