Liquid crystal display device and repair structure with electrode overlapped to data line
View Patent ↗A liquid crystal display device with a repair structure that facilitates repair of a short circuit or an open circuit. In the device, a gate line is formed on an insulating substrate and a gate electrode is integral to the gate line. A semiconductor layer is formed on the gate electrode with having an insulating film therebetween. A data line is crossed with the gate electrode, and a source electrode is integral to the data line on the semiconductor layer and the gate electrode. A drain electrode is spaced oppositely the source electrode. A protective film has a first contact hole at the drain electrode. A pixel electrode is formed on the protective film and is connected, via the contact hole, to the drain electrode. The pixel electrode has an area overlapped partially with the data line and is spaced from the gate line by a desired length (α) at one or more corners thereof. A storage electrode extends from the pixel electrode to be overlapped partially with the gate line and is spaced from the data line by a desired width (δ) at one or more corners thereof.
1. A repaired liquid crystal display device, comprising:
a gate line formed on a substrate;
a gate insulator on the gate line;
a data line intersecting the gate line;
a protective film formed on the data line;
a pixel electrode formed on the protective film, wherein the pixel electrode is spaced apart from the gate line and overlaps only with the data line; and
a storage electrode interposed between the gate insulator and the protective film,
wherein the storage electrode includes an overlapping part overlapping with the gate line and an extending part extending from the overlapping part,
wherein the extending part overlaps with the pixel electrode, and
wherein the pixel electrode is in connected with the extending part via a contact hole formed at the protective film.
