  • Publication number: 20090257006
    Abstract: A color filter is described, including a first color filter layer, a first light absorbing layer, a second color filter pattern and a second light absorbing pattern. The first color filter layer is disposed over a substrate. The first light absorbing layer is disposed between the substrate and the first color filter layer. The second color filter pattern covers a portion of the first color filter layer. The second light absorbing pattern is disposed between the second color filter pattern and the first color filter layer.

  • Publication number: 20080124823
    Abstract: Method of fabricating patterned layers using lift-off processes is disclosed. A patterned stacked layer is formed on a substrate. The patterned stacked layer consists of a sacrificed layer and a photoresist layer, which covers and extends out of the sacrificed layer. Next, a film layer having a thickness smaller than that of the sacrificed layer is formed on the patterned stacked layer and gaps between the patterned stacked layer. Then, the photoresist layer and the film layer disposed on the photoresist layer are removed using a lift-off process; finally the sacrificed layer is removed.

  • Publication number: 20080062376
    Abstract: A method of fabricating a liquid crystal panel is provided. First, a first substrate having a pixel array thereon is provided. Next, a sealing frame is formed on the first substrate around the pixel array. Next, a liquid crystal inkjet printing step is conducted to the region surrounded by the sealing frame to perform an alignment process. Then, the liquid crystal inkjet printing step is still performed to fill a liquid crystal material within the region surrounded by the sealing frame. Thereafter, a second substrate having an electrode layer thereon is provided. Then, the first and second substrates are assembled together through the sealing frame.
