Patent abstract

A pixel structure fabricating method is provided. A gate is formed on a substrate. A gate insulation layer covering the gate is formed on the substrate. A channel layer, a source, and a drain are simultaneously formed on the gate insulation layer above the gate. The gate, channel layer, source, and drain form a thin film transistor (TFT). A passivation layer is formed on the TFT and the gate insulation layer. A black matrix is formed on the passivation layer. The black matrix has a contact opening above the drain and a color filter containing opening. A color filer layer is formed within the color filter containing opening through inkjet printing. A dielectric layer is formed on the black matrix and the color filter layer. The dielectric layer and the passivation layer are patterned to expose the drain. A pixel electrode electrically connected to the drain is formed.
