The transparent pixels are disposed within a grid defined by the first through (N)-th vertical constant voltage lines and the first through (M)-th horizontal constant voltage line groups.

The first substrate includes a plurality of color pixels and a white pixel that outputs a second white light having a same gray scale as a first white light formed by mixing light outputted from the plurality of color pixel. The white pixel is activated by a second current that is lower than a first current that activates the color pixels.

An organic light emitting display device may include a substrate having a pixel region and a transparent region, a first capacitor disposed in the transparent region of the substrate, a semiconductor device disposed in the pixel region of the substrate, a second capacitor disposed on the semiconductor device, and an organic light emitting structure disposed on the second capacitor. The organic light emitting display device may have a sufficient capacitance for components including the semiconductor device and the organic light emitting structure without increasing an area of the pixel region while maintaining a transmittance of the organic light emitting display device.

Organic light emitting display devices and methods of manufacturing organic light emitting display devices

An organic light emitting display device includes a substrate a plurality of pixels disposed along a first direction and a second direction, the first direction and the second direction being substantially parallel to a top surface of the substrate and substantially perpendicular to each other, first wirings which is disposed on the substrate, extends in the first direction, and includes a first low voltage power line, and second wirings which is disposed on the substrate, extends in the second direction, and includes a second low voltage power line electrically connected to the first low voltage power line.

In a liquid crystal display (LCD), a thickness of a passivation layer overlapping signal lines is larger than a thickness of portion of the passivation layer not overlapping signal lines. A spacer may be formed to overlap the signal lines. In an aperture region of the LCD, a thickness of the passivation layer between a common electrode and a pixel electrode is relatively small, and therefore, it may be possible to prevent reduction in the intensity of the electric field between the common electrode and the pixel electrode. Since thickness of the passivation layer may be relatively large, it may be possible to prevent a signal delay of common voltage. A spacer may be formed overlapping signal lines with relatively thick passivation layer. The spacer may have a small height. Cell gap may be adjusted to be uniform, and prevent reduction in aperture ratio of the LCD.

Liquid crystal display and manufacturing method thereof

A liquid crystal display (LCD) includes a pixel unit having pixels, each of the pixels positioned at a corresponding intersection of gate lines and data lines. A drive circuit unit is positioned at one side of the pixel unit to supply driving signals to the gate lines and the data lines. Test pads are connected to the data lines. In the LCD, each of the data lines is electrically connected between the pixel unit and the drive circuit unit via one or more lines among a first line formed in a first layer and a second line formed in a second layer, and wherein each of the data lines is connected to a different test pad from the test pad connected to adjacent data lines in each of the first and second layers.

Liquid crystal display

A liquid crystal display uses a layout which reduces the number of data lines relative to the number of pixel columns by providing one data line for every two pixel columns. The display is structured to prevent a passivation layer from becoming opaque due to a manufacturing haze effect by forming the pixel electrode below a gate insulating layer. It is structured to prevent a drain electrode from being damaged due to an etchant used for patterning the pixel electrode. Further, it is structured to prevent a short circuit between a common voltage line and a gate line while not substantially reducing an aperture ratio by disposing a common voltage contact hole for electrically connecting the common voltage line with a common electrode between vertically extending portions of two gate lines that generally extend horizontally.

A liquid crystal display device and a method of manufacturing the same are provided. The liquid crystal display device is manufactured by placing a half tone mask on the assembled first and second substrates in a polymerization process of liquid crystal composition disposed between the first and second substrates. The liquid crystal composition includes liquid crystal molecules and reactive mesogens. The half tone mask has a first transmission part and a second transmission part. The light transmittance of the first transmission part is higher than the light transmittance of the second transmission part. The first transmission part is disposed in the pixel region, while the second transmission part is disposed in the non-pixel region. The non-pixel region is covered by a black matrix that is formed on the second substrate. Through this manufacturing method, the generation of spots around a black matrix is prevented.

Liquid crystal display device and method of manufacturing the same

A display apparatus includes a thin film transistor having a top-gate structure and a storage capacitor that are arranged on a first substrate. An upper electrode of the storage capacitor has a size larger than a size of a lower electrode, so as to cover an entire surface of the lower electrode in a plan view. Thus, electric field caused by static electricity may be prevented from accumulating at a corner of the upper electrode when the electric filed flows from the lower electrode to the upper electrode, thereby preventing an intermediate insulating layer from being burnt.
