    摘要: A method for manufacturing a pixel structure is provided. A gate and a gate insulating layer are sequentially formed on a substrate. A semiconductor layer and a second metal layer are sequentially formed on the gate insulating layer. The semiconductor layer and the second metal layer are patterned to form a channel layer, a source and a drain by using a patterned photoresist layer formed thereon, wherein the source and drain are disposed on a portion of the channel layer. The gate, channel, source and drain form a thin film transistor. A passivation layer is formed on the patterned photoresist layer, the gate insulating layer and the thin film transistor. Then, the patterned photoresist layer is removed, such that the passivation layer thereon is removed simultaneously to form a patterned passivation layer and the drain is exposed. A pixel electrode is formed on the patterned passivation layer and the drain.

    摘要: A method for fabricating a pixel structure using a laser ablation process is provided. This fabrication method forms a gate, a channel layer, a source, a drain, a passivation layer, and a pixel electrode sequentially by using a laser ablation process. Particularly, the fabrication method is not similar to a photolithography and etching process, so as to reduce the complicated photolithography and etching processes, such as spin coating process, soft-bake, hard-bake, exposure, developing, etching, and stripping. Therefore, the fabrication method simplifies the process and thus reduces the fabrication cost.

A patterned passivation layer is formed on the substrate and the active device, and the patterned passivation layer exposes a portion of the active device. Then, a conductive layer is formed over the patterned passivation layer, and the conductive layer is electrically connected to the active device. A mask exposing a portion of the conductive layer is provided above the conductive layer. A laser is used to irradiate the conductive layer via the mask to remove the portion of the conductive layer exposed by the mask. As a result, the remained portion of the conductive layer constitutes a pixel electrode, and the pixel electrode is electrically connected to the active device. The method simplifies the fabrication process of a pixel structure, and thus reduces the fabrication cost.
