Active Device Array Substrate

An active device array substrate comprising:

• a flexible substrate having at least one transistor region and at least one transparent region adjacent to each other;
• a gate electrode disposed on the transistor region of the flexible substrate;
• a dielectric layer covering the gate electrode and the flexible substrate, a portion of the dielectric layer disposed on the gate electrode and having a first thickness, another portion of the dielectric layer disposed on the transparent region of the flexible substrate and having a second thickness, wherein the second thickness is less than the first thickness;
• a channel layer, a source electrode, and a drain electrode disposed on the dielectric layer which is disposed on the transistor region, the channel layer disposed above the gate electrode, the source electrode and the drain electrode disposed on opposite sides of the channel layer and electrically connected to the channel layer;
• and
• a pixel electrode disposed on the dielectric layer which is disposed on the transparent region, the pixel electrode electrically connected to the drain electrode.
