Abstract
A pixel structure including an active device, a capacitor electrode line, a light shielding layer, a color filter pattern and a pixel electrode is provided. The active device and the capacitor electrode line are disposed on a substrate. The light shielding layer is disposed on the substrate, and the dielectric constant of the light shielding layer is less than 6. The light shielding layer defines a unit area on the substrate, and a contact hole is formed in the light shielding layer above the active device. A color filter pattern is disposed in the unit area, wherein the dielectric constant of the color filter pattern is less than 6, and the color filter pattern does not fill into the contact hole. The pixel electrode is disposed on the color filter pattern, in which the pixel electrode fills into the contact hole so as to electrically connect with the active device.
