Abstract: The present invention is intended to control the color temperature of white exhibited by a liquid crystal display device. White is produced when light waves emitted through pixels associated with three colors of red, green, and blue have maximum intensities. The amounts of light emitted through the respective pixels are controlled by differentiating the shapes of the pixel electrodes disposed at the respective pixels from one another. Thus, the color temperature of white is controlled. Otherwise, the shapes of interceptive films disposed at the respective pixels are differentiated from one another in order to control light waves emitted through the respective pixels. Thus, the color temperature of white is controlled. The interceptive film may be shaped like the pixel electrode. Otherwise, the interceptive film may be realized with an interceptive pattern other than that of the pixel electrode or one of openings bored in a black matrix.

Abstract: Disclosed embodiments relate to a thin-film transistor (TFT) for use in a display device. The display device may include a liquid crystal display (LCD) panel having multiple pixels arranged in rows and column, with each row corresponding to a gate line and each column corresponding to a source line.

For each TFT, holes may be formed in the gate line in a region beneath the source and/or the drain. The holes may be formed such that the source and drain only partially overlap the holes. The presence of the holes reduces the area of the gate line, which may reduce parasitic capacitance and improve loading. This may provide improved panel performance, which may reduce the appearance of certain visual artifacts.

Since the area of contact between the columnar spacer and the TFT substrate is decreased, it is possible to suppress scraping of the alignment film and thus to prevent occurrence of bright spots.
