ABSTRACT:
An array substrate device has a color filter-on-thin film transistor (COT) structure for use in a liquid crystal display device. The array substrate device includes a gate line disposed in a first direction on a substrate; a data line disposed over the substrate in a second direction, the data line perpendicularly crossing the gate line to define a pixel region; a thin film transistor near a crossing of the gate and data lines, the thin film transistor including a gate electrode, a semiconductor layer, a source electrode and a drain electrode; a capacitor electrode overlapping the gate line; a color filter having an island pattern corresponding to the pixel region, the color filter exposing portions of the drain electrode and the capacitor electrode; and a pixel electrode disposed over the cover filter, corresponding to the pixel region, and contacting the portions of the drain electrode and the capacitor electrode.
