摘要
A liquid crystal display (LCD) includes an array of pixels over a thin film transistor (TFT) substrate. The TFT substrate includes a TFT that has a first metal layer to form a gate electrode and a second metal layer to form a source electrode and a drain electrode for each pixel. The LCD also includes an organic insulation layer disposed over the TFT substrate, where the organic insulator layer has trenches on a top surface. The LCD further includes a third metal layer disposed over the organic insulation layer in the trenches, the trenches having a trench depth at least equal to the thickness of the third metal layer. The LCD also includes a passivation layer over the third metal layer, and a pixel electrode for each pixel over the passivation layer. The LCD further includes a polymer layer over the pixel electrode, and liquid molecules on the polymer layer.
