  • Patent number: 10074504
    Abstract: A liquid crystal display device that includes an array substrate, an opposite substrate and a liquid crystal display layer is described. The array substrate includes a pixel electrode and a lower alignment layer. The pixel electrode has a plurality of slit portions extending in different directions. The lower alignment layer includes a reactive mesogen (RM) diamine is formed on the pixel electrode to induce an alignment direction of the liquid crystal molecules. An upper alignment layer is formed on a common electrode of the opposite substrate. The RM is cured at surfaces of the lower and upper alignment layers in response to ultraviolet (UV) light, so that liquid crystal molecules have a pretilt angle. Therefore, the aperture ratio and the response time may be improved, and afterimages may be decreased, so that display quality may be improved.

  • Patent number: 9897793
    Abstract: A substrate for an electrowetting display device including a pixel electrode, a partition wall pattern and a water-repellent pattern. The pixel electrode is formed on a base substrate. The partition wall pattern is disposed along an edge of the pixel electrode to expose the pixel electrode. The water-repellent pattern is disposed at a space formed by the pixel electrode and the partition wall pattern to be extended along a lower portion of side surfaces of the partition wall pattern from an area on which the pixel electrode is formed. The water-repellent pattern exposes an upper portion of the side surfaces and an upper surface of the partition wall pattern. Thus, a manufacturing reliability of a substrate for an electrowetting display device is improved to prevent a display quality from being reduced.
