Claim 0:
1. A liquid crystal display device comprising:
a first substrate;
a second substrate that is disposed so as to be opposed to the first substrate;
a semiconductor layer disposed in a pixel on the first substrate;
a drain electrode electrically connected to the semiconductor layer;
an organic insulating film formed on the semiconductor layer and covering a part of the drain electrode;
a first opening that penetrates the organic insulating film and exposing the drain electrode;
an island-shaped electrode disposed on the first opening and the organic insulating film, and electrically connected to the drain electrode;
an inorganic insulating film disposed on the organic insulating film, the drain electrode, and the island-shaped electrode in the first opening;
a second opening that penetrates the inorganic insulating film and exposing the drain electrode; and
a pixel electrode formed on the inorganic insulating film and electrically connected to the island-shaped electrode through the second opening,
wherein the drain electrode is directly contacted with the inorganic insulating film and the island-shaped electrode in the first opening, and
a peripheral end portion of the island-shaped electrode is covered with the inorganic insulating film.
