Abstract: The present disclosure provides an optical film layer including a first transparent cover layer, a second transparent cover layer, an ink layer, and a connection layer. The second transparent cover layer is disposed over the first transparent cover layer. The ink layer is disposed on an edge region of a surface of the second transparent cover layer. The connection layer is disposed between the ink layer and the first transparent cover layer and between the surface of the second transparent cover layer and the first transparent cover layer to connect the first transparent cover layer and the second transparent cover layer. By disposing the ink layer between the first transparent cover layer and the second transparent cover layer, a problem of light leaking from an edge of a view area is solved and a display device is thinned, thereby enhancing a display quality of the display device.
