Light shading structure, and color filter substrate, active device array substrate, liquid crystal display panel thereof

An active device array substrate, comprising:

• a substrate, having a display region and a non-display region;
• a plurality of scan lines and data lines, disposed in the display region;
• a plurality of active devices, disposed in the display region on the substrate, wherein each active device is electrically connected with one of the scan lines and one of the data lines;
• a plurality of pixel electrodes, disposed in the display region on the substrate, wherein each pixel electrode is respectively electrically connected with one of the active devices;
• a light shading structure, disposed on the substrate, and comprising:
• a black matrix layer, disposed on the substrate, and used for defining a plurality of sub-pixel regions in the display region and covering the non-display region adjacent to the edge of the display region;
• a light shading layer, disposed on the black matrix layer of the non-display region adjacent to the edge of the display region;
• and
• a plurality of color filter units, correspondingly disposed in the sub-pixel regions.
