1. Field of the Invention
The present invention relates to a liquid crystal display technology, and more particularly, to a liquid crystal panel and method for manufacturing the same.
2. Description of Prior Art
Nowadays, liquid crystal displays (LCDs) have been widely used in displaying 3D images. For example, a 3D liquid crystal display equipped with a film-type patterned retarder (FPR) is developed. In the 3D liquid crystal panel, 3D viewing angle is an important indication, which represents a range of angles a viewer at a certain distance is able to see the 3D images.
The 3D viewing angle can be improved by increasing the size of a black matrix (BM) in a color filter substrate of the liquid crystal panel. However, this approach is merely suitable for large-scale liquid crystal panels. If the liquid crystal panel is relatively small in size, increasing the size of BM may result in dramatic decrease of an aperture ratio.
In conventional skills, the black matrix will be disposed at both sides of the color filter substrate. In such a manner, the 3D viewing angle of the 3D liquid crystal panel can be greatly improved at the cost of decreasing a small amount of the aperture ratio.
