Abstract
A method for fabricating a liquid crystal display (LCD) device is disclosed, in which an aperture ratio is increased by reducing an area of a drain electrode which applies an electrical signal to a pixel electrode of a pixel region. In the LCD device, a contact hole where the drain electrode of TFTs is electrically connected to the pixel electrode is formed over predetermined portions of the drain electrode and the pixel region.
Claims12
A liquid crystal display device provided with a plurality of gate lines, a plurality of data lines, and a plurality of TFTs, the gate lines crossing the data lines to define a pixel region and the TFTs being formed at crossing points of the gate and data lines, wherein a contact hole that electrically connects a drain electrode of the TFTs with a pixel electrode of the pixel region is formed over predetermined portions of the drain electrode and the pixel region.
A liquid crystal display device comprising:
- gate lines arranged to cross data lines on a substrate, thereby defining a pixel region;
- thin film transistors, each having a gate electrode and source and drain electrodes, formed at crossing points of the gate lines and the data lines;
- a contact hole formed over the drain electrode and the pixel region;
- and
- a pixel electrode formed in the pixel region for connecting the pixel electrode to the drain electrode through the contact hole.
A method for fabricating the liquid crystal display device comprising:
- forming thin film transistors each having a gate electrode, a source electrode and a drain on an insulating substrate;
- forming a passivation film on an entire surface of the substrate including the thin film transistors;
- forming a contact hole over a predetermined portion of the drain electrode and a pixel region adjacent to the drain electrode;
- and
- forming a pixel electrode in the pixel region connected to the drain electrode through the contact hole.
