Display substrate and method of manufacturing the same
View Patent ↗A display substrate includes a gate electrode, a gate insulating layer, and a semiconductor layer that are sequentially formed on a substrate. Also, the display substrate includes a color filter layer formed on the substrate and exposing a portion of the semiconductor layer, and source and drain electrodes that each overlap with the semiconductor layer and the color filter layer. The gate electrode, the gate insulating layer, and the semiconductor layer have the same shape as each other, and the gate electrode is insulated from the gate insulating layer and the semiconductor layer by the color filter layer.
1. A display substrate, comprising:
a substrate;
a gate electrode arranged on the substrate;
a gate insulating layer arranged on an area corresponding to an area where the gate electrode is formed;
a semiconductor layer arranged on an area corresponding to an area where the gate insulating layer is formed;
a color filter layer arranged on the substrate and exposing the semiconductor layer;
a source electrode arranged on the color filter layer and the semiconductor layer;
a drain electrode spaced apart from the source electrode and arranged on the color filter layer and the semiconductor layer;
a protective layer arranged on the semiconductor layer, the source electrode, and the drain electrode; and
a pixel electrode arranged on the protective layer and connected to the drain electrode,
wherein the gate electrode, the gate insulating layer, and the semiconductor layer have the same shape as each other in a plan view.
2. The display substrate of claim 1 , wherein the color filter layer covers a portion of the semiconductor layer.
3. The display substrate of claim 2 , wherein a distance between the source electrode and the drain electrode is defined by the color filter layer.
4. The display substrate of claim 1 , wherein the substrate comprises a transparent plastic material.
5. The display substrate of claim 4 , wherein the plastic material comprises a material selected from the group consisting of kapton, polyethersulphone (PES), polycarbonate (PC), polyimide (PI), polyethyleneterephthalate (PET), polyethylenenaphthalate (PEN), polyacrylate (PAR), and fiber reinforced plastic (FRP).
6. The display substrate of claim 1 , further comprising a storage line arranged on the color filter layer.
