  • Liquid crystal display device and method of manufacturing the same
    Patent number: 7535540
    Abstract: Provided is an LCD that can be manufactured by a simplified process. The LCD includes first and second substrates, and a liquid crystal layer interposed between the first and second substrates. TFTs are formed in a pixel region defined on the first substrate. A photosensitive material is coated on each of the TFTs, and light is irradiated by a photo mask including a full open region, a half open region and a closed region. Accordingly, the photosensitive material is removed from the pixel region, and a passivation layer and a spacer are simultaneously formed on each of the TFTs. A transparent conductive pattern is formed on the spacer together with a pixel electrode formed in the pixel region, and is electrically connected to a common electrode of the second substrate.
