  • Patent number: 7554646
    Abstract: In a method of fabricating a liquid crystal display device, when a photoresist film formed on a substrate for the liquid crystal display device is exposed and developed, protrusions are formed on the substrate for increasing a viewing angle of the liquid crystal display device. Although the substrate is formed with step differences thereon caused by various intermediate films, the protrusions may have a same size since an exposure amount to the photoresist film is varied according to the step differences of the substrate on which the protrusions are formed. Thus, the liquid crystal display device may have an improved display quality.

  • Publication number: 20090091689
    Abstract: In a display device, first and second substrates parallel to each other are arranged between first and second polarizers that are parallel to each other. A liquid crystal layer is arranged between the first and second substrates, and a light emitting layer having a quantum dot structure is arranged on the first polarizer. Also, a light source that emits a blue light is arranged under the second polarizer. Thus, the display device may improve a light utilizing efficiency, thereby improving a display quality.

  • Publication number: 20080239188
    Abstract: A display substrate includes a base substrate, a thin-film transistor (TFT), a pixel electrode, a pad part, and a cell-gap compensating part. The base substrate has a display region, a seal region surrounding the display region, and a peripheral region surrounding the seal region. The TFT is in the display region. The pixel electrode is connected to a drain electrode of the TFT and contacts the base substrate. The pad part is interposed between a first side of the base substrate and the seal region and is connected to the TFT through a first transmission line. The cell-gap compensating part is in the seal region and includes a compensating pattern adjacent to a second side of the base substrate and an insulating pattern on the compensating pattern.

  • Publication number: 20070121054
    Abstract: A display substrate includes a transparent plate and a liquid crystal dispersion adjuster. The display substrate includes a display area and a peripheral area surrounding the display area. The liquid crystal dispersion adjuster is formed in the peripheral area to modify the movement of the liquid crystal. The dispersion adjuster includes enhancing parts and a suppression part. The enhancing parts increase the dispersion of the liquid crystal, and the suppression part reduces the dispersion of the liquid crystal, thereby reducing non-filling area of the liquid crystal and the contamination of a seal-line.

  • Publication number: 20070076158
    Abstract: A liquid crystal display device includes a substrate, liquid crystal disposed on the substrate, and a protrusion to influence on the alignment of the molecules of the liquid crystal to increase a viewing angle. The protrusion includes portions with different sizes, depending on the desired control power of the protrusion on the alignment of the molecules. That is, the portion size increases in the area where more control power is desired, and the portion size decreases in the area where less control power is desired. The protrusion is formed by depositing and pattering a thick photoresist. At the same time, a spacer can be formed.
