  • Patent number: 6486935
    Abstract: A liquid crystal display device which can improve aperture ratio by minimizing light blocking is disclosed. In a liquid crystal display device according to the present invention, gate lines and data lines are arranged to be overlapped with each other, thereby increasing light transmittance region. Furthermore, TFT is disposed between the gate line and data line, thereby further increasing light transmittance region. As a result, aperture ratio is improved.

  • Patent number: 6204082
    Abstract: A method of manufacturing a liquid crystal display device which can easily planarize the surface of a substrate and obtain a high aperture ratio, is disclosed. According to the present invention, firstly a first metal layer is formed a transparent insulating substrate. The portion of the first metal layer is then anodized, to define a gate and to form a first oxide layer on the substrate at both sides of the gate. Next, a gate insulating layer is formed on the overall substrate and a channel layer is formed on the gate insulating layer over the gate. Ohmic layers are then formed on the gate insulating layer to be overlapped with both side of the channel layer and a second metal layer is formed on the overall substrate. Thereafter, the portion of the second metal layer is anodized, to define source and drain on the ohmic layers and to form a second oxide layer. An insulating layer is then formed on the overall substrate and etched to expose the portion of the source, thereby forming a contact hole.
