  • Publication number: 20090190054
    Abstract: A display substrate includes a plurality of transistors, a plurality of color filters, a plurality of pixel electrodes, a plurality of supporting members, and a plurality of filling members. The transistors are connected to a plurality of gate lines extending in a first direction on a base substrate and a plurality of data lines extending in a second direction crossing the first direction. The color filters are disposed over the transistors, and have a plurality of holes. The pixel electrodes are disposed on the color filters, and electrically connect to the transistors. The supporting members are disposed on the color filters, and maintain a gap between the base substrate and a substrate opposing the base substrate. The filling members are comprised of the same material as the supporting members, and fill the holes.

  • Publication number: 20090121232
    Abstract: An array substrate, a method for manufacturing the array substrate and a display panel having the array substrate are presented. The method includes forming a thin-film transistor (TFT) on a base substrate. A passivation layer covers the TFT. A color filter layer is formed on the passivation layer. An organic protective layer is formed on the color filter layer, and has a type of photoresist that is substantially the same as that of the color filter layer. A contact hole is formed through the organic protective layer, the color filter layer and the passivation layer, partially exposing the TFT. A pixel electrode is formed on the organic protective layer to be electrically connected to a portion of the TFT. The contact hole may be formed through the organic protective layer, the color filter layer and the passivation layer by a single photolithography process, simplifying the array substrate manufacturing process.
