In the result, the depression (60) in a surface of the glass substrate (10) is repaired by a transparent resin (65) obtained through the copolymerization of the plural types of starting material. Therefore, the glass substrate (10) can be repaired at a low temperature without performing a sintering process. Further, the transparent resin (65) has a reticular structure obtained through random copolymerization of the plural types of starting material and, as such, has its optical anisotropy suppressed, thus preventing the emergence of an unintended luminescent spot or the like on a liquid crystal display panel.
Liquid crystal display and manufacturing method thereof
A liquid crystal display includes a substrate, a plurality of pixel electrodes formed on the substrate, a common electrode facing the pixel electrodes, and a liquid crystal layer interposed between the pixel electrodes and the common electrode. The pixel electrode includes at least one oblique edge including a plurality of protruded and depressed portions.
Liquid crystal display
A liquid crystal display having an improved pixel aperture ratio includes vertical scan lines disposed between adjacent pixels, video signal lines disposed between adjacent pixels, and sub-capacitor lines disposed between adjacent pixels while regularly and repeatedly crossing the vertical scan lines.
Array substrate and display device having the same
An array substrate includes a lower substrate, a switching element and a pixel electrode. In the lower substrate, unit pixel areas are each divided into a plurality of domains. The switching element is disposed on the lower substrate and transmits a pixel signal. The pixel electrode is disposed on the unit pixel area and is electrically connected to the switching element. The pixel electrode includes a plurality of slit portions disposed thereon. A portion of the slit portions is longitudinally extended in a zigzag shape along different directions in correspondence with the domains.
Alignment substrate for aligning liquid crystal molecules, liquid crystal display panel having the same, and method of manufacturing the alignment substrate
The present invention discloses an alignment substrate that includes a base substrate and an alignment layer arranged on the base substrate. A plurality of unit pixels is defined in the base substrate. The alignment layer includes at least two sub-alignment portions dividing the unit pixel into at least two domains. Each sub-alignment portion is arranged in a different domain of the at least two domains and is aligned to have a different pretilt direction from the other sub-alignment portions.
