  • Patent number: 7414679
    Abstract: The present invention relates to a display panel comprising a circuit structure, which comprises at least one data line and a pixel electrode. There is a dummy data line provided between the pixel electrode and the data line, wherein the data line has at least two protrusions extending to the corresponding position of the dummy data line. When the data line is disconnected, repair can be made by welding the protrusions and the dummy data line by laser, and thus no extra circuit is needed.

  • Patent number: 7211303
    Abstract: An alignment film for avoiding the degradation of the charge holding rate of a LCD, due to ionic impurity of the liquid crystal materials, and the LCD that is made of the same is disclosed herein. The alignment film 10 includes derivatives of polyimides or polyamides and low molecular thermosetting resins having a viscosity of 1–3000 Poise within the temperature of 25° C. Through the use of the alignment film 10 produced by the thermosetting resin monomers, the ionic impurity is prevented from contact with the pixel electrode 16. The performance of the LCD with the alignment film is improved during the test of reliability, even though a liquid crystal material with high dielectric anisotropy is used.
