Abstract
An active device array substrate including a substrate, a plurality of scan lines, a plurality of data lines, a plurality of active devices, a first passivation layer, a transparent pad layer, a plurality of color filter patterns, a second passivation layer, a plurality of pixel electrodes, and a black matrix layer is provided. Each of the active devices is electrically connected to one of the scan lines and one of the data lines, respectively. The transparent pad layer having a plurality of openings for accommodating the color filter patterns is disposed on the first passivation layer located above the scan lines and the data lines. The first passivation layer, the color filter patterns and the second passivation layer have a plurality of contact windows therein. The black matrix layer is disposed above the transparent pad layer to cover a portion of the pixel electrodes.
