Abstract
The present invention relates to a light guide plate structure including a light guide layer and at least a light-barrier line. The light-barrier line includes an ink and is disposed within the light guide layer for blocking a light from being transmitted all over the light guide layer, and the light-barrier line is employed to allow the light to be just transmitted in separated regions within the light guide layer or to prevent light leakage. The present invention also relates to fabrication of the aforesaid light guide plate structure, in which, a surface modification is performed on the light guide layer, and a modified surface of the light guide layer is printed with an ink to allow the ink to permeate or corrode the light guide layer to form a light-barrier line within the light guide layer.
