Abstract
A light shading structure suitable for being disposed on a substrate is provided, wherein the substrate has a display region and a non-display region. The light shading structure includes a black matrix layer and a light shading layer. The black matrix layer is disposed on the substrate and defines multiple sub-pixel regions in the display region. The black matrix layer also covers the non-display region adjacent to the edge of the display region. The light shading layer is disposed on the black matrix layer in the non-display region adjacent to the edge of the display region and has at least one channel. The light shading structure can reduce light leakage at the edge of the display region of the LCD panel. During processes of manufacturing the LCD panel, the liquid crystal contamination caused by the contact of liquid crystal and sealant can be avoided by the light shading structure.
