OPTICAL FILM AND DISPLAY MODULE USING THE SAME
An optical film includes a hard coating layer, an anti-glare layer, a first adhesive layer, and a second adhesive layer. The hard coating layer is a hard and transparent material, and the anti-glare layer is adhered on a first side of the hard coating layer. The first adhesive layer is adhered on one side of the anti-glare layer away from the hard coating layer, and the second adhesive layer is adhered on a second side of the hard coating layer opposite to the first side. A thickness of the optical film can be 0.19˜0.23 mm. The present disclosure further provides a display module using the optical film.
