Abstract:
1. A liquid crystal display panel, comprising: a first substrate; a plurality of scan lines and a plurality of data lines disposed on the first substrate; an insulation layer, disposed between the scan lines and the data lines; a plurality of thin film transistors (TFT) disposed on the first substrate, wherein each of the TFTs comprises a gate, a channel layer, a source and a drain, the gate is electrically connected to one of the scan lines, and the source is electrically connected to one of the data lines; a plurality of pixel electrodes, wherein each of the pixel electrodes is electrically connected to the drain of one of the TFTs; a plurality of retaining wall patterns disposed on the insulation layer, wherein each of the retaining wall patterns is a single layer structure, and the material thereof is the same as that of the source and drain; a second substrate, disposed opposite to the first substrate; a liquid crystal layer disposed between the first substrate and the second substrate; and a plurality of pillar spacers disposed between the second substrate and the first substrate, wherein one end of each pillar spacer is disposed inside one of the retaining wall patterns on the first substrate.
