Abstract:
1. A pixel structure suitable for being disposed on a substrate, the pixel structure comprising: a gate disposed on the substrate; a gate dielectric layer disposed on the substrate to cover the gate; a patterned semiconductor layer disposed on the gate dielectric layer and having a channel area located above the gate; a patterned dielectric layer disposed on the patterned semiconductor layer and comprising an etching-stop layer disposed above the gate and a plurality of bumps; a patterned metal layer comprising a source, a drain and a reflective pixel electrode connected to the drain, wherein the source and the drain respectively cover portions of the channel area, the reflective pixel electrode covers the bumps to form an uneven surface, and the gate, the gate dielectric layer, the patterned semiconductor layer, the source and the drain together form a transistor; an overcoat dielectric layer disposed on the transistor, wherein the overcoat dielectric layer comprises a contact opening to expose a portion of the reflective pixel electrode; and a transparent pixel electrode disposed on the overcoat dielectric layer and electrically connected to the reflective pixel electrode through the contact opening.
