  • Publication number: 20040239837
    Abstract: Pixels of red, blue and green are sequentially arranged in the row direction. The red and green pixels are alternately arranged in the column while the blue pixels being arranged between the neighboring red and each blue pixel is surrounded by the four red and green pixels. Gate lines are arranged at respective pixel rows. Data lines cross over the gate lines in an insulating manner and are arranged at the respective pixel columns. Pixel electrodes and thin film transistor are arranged at the respective pixels. At a predetermined pixel unit, the data lines to the two blue pixel are connected to each other. The pixel electrodes are overlapped with the gate lines or data lines via a passivation layer of low dielectric organic material or insulating material such as SiOC, SiOF.

  • Publication number: 20040241987
    Abstract: A gate wire is formed on a substrate. Next, after forming a gate insulating film, a semiconductor layer and an ohmic contact layer subsequently are formed thereon. Next, a data wire is formed. Next, a passivation layer and an organic insulating film are deposited, and patterned to form contact holes for exposing the drain electrode, the gate pad and the data pad respectively. Here, the organic insulating film around the contact holes is formed thinner than that in the other portions. Next, the organic insulating film around the contact holes is removed by an ashing process to expose the borderline of the passivation layer in the contact holes, thereby removing an under-cut. Then, a pixel electrode, an assistant gate pad and an assistant data pad respectively connected to the drain electrode, the gate pad and the data pad are formed.

  • Publication number: 20040051103
    Abstract: A black matrix having an opening at pixels of a matrix array in a display area, a common wire including common pads and common signal lines, and gate pads in a peripheral area, and an alignment key in outer area to align interlayer thin films are formed on an insulating substrate. Red, blue and green color filters the edge of which overlap the black matrix are formed at the pixels on the insulating substrate, and an organic insulating layer covering the black matrix and the color filters and having a contact hole exposing the gate pad is formed thereon. A gate wire including a gate line connected to the gate pad through the contact hole and a gate electrode connected to the gate line is formed on the organic insulating layer, and a gate insulating layer covering the gate wire is formed on the organic insulating layer. A semiconductor pattern and ohmic contact layers are sequentially formed on the gate insulating layer of the gate electrode.
