  • Patent number: 9165946
    Abstract: An array substrate includes a scan line, a data line, a thin film transistor, a first transparent electrode, a passivation layer, and a second transparent electrode. The scan line and the data line interlace to define a pixel region. The gate dielectric layer of the thin film transistor overlaps the scan line and the data line and extends to cover the pixel region. The gate dielectric layer has a first region, a second region, and a third region. The first region corresponds to the semiconductor layer of the thin film transistor. The second region connects the first region and the third region. The thickness of the second region is different from that of the third region. The first transparent electrode covers the gate dielectric layer in the pixel region. The passivation layer covers the thin film transistor and the first transparent electrode. The second transparent electrode covers the passivation layer.
