  • Patent number: 9935132
    Abstract: A pixel structure including scan lines, data lines, and sub-pixels is provided. The scan and data lines are disposed on the substrate. The sub-pixels include switch devices, contact pattern layer, color filter pattern layers, and pixel electrodes. The switch devices are electrically connected to one scan line and one data line respectively. The contact pattern layer and the color filter pattern layer are disposed on the substrate and the switch devices. The contact pattern layer covers part of two adjacent switch devices. At least two color filter pattern layers include a patterned opening respectively, and the contact pattern layer is disposed in the patterned opening. The pixel electrodes are disposed on the color filter pattern layer, the contact pattern layer, and the switch device. At least one pixel electrode is partially disposed between the color filter pattern layer and the corresponding switch device while electrically connected to the switch device.
