A COT(Color filter on TFT) structure array substrate for an LCD(Liquid Crystal Display) and a manufacturing method thereof are provided to supply an image of superior quality by preventing current leakage, wavy noise, and aperture ratio reduction. An array substrate(200) comprises a gate line(212), a data line(230), a gate electrode(214), an active layer, an ohmic contact layer, a source electrode(232), a drain electrode(234), a source electrode connection pattern, a pixel electrode(260), and a color filter. The gate line and the data line intersect on the substrate to define a pixel region. The gate electrode is connected to the gate line. The active layer has an island shape on a gate electrode upper potion. The ohmic contact is spaced in an upper part of the active layer. The source electrode and drain electrode are spaced from each other, and have the same shape as the ohmic contact on the ohmic contact layer. The source electrode connection pattern connects the source electrode to the data line. The pixel electrode extends from the drain electrode to the pixel region. The color filter is formed in the pixel region. |
