A display device, capable of changing view angle range and suitable for reducing thickness and weight, is provided. One compensating panel has such a structure that two polymer films, having birefringence, adhere to each other. The birefringence directions of the polymer films are parallel or orthogonal to the liquid crystal orientation direction. Similarly, another compensating panel has such a structure that two polymer films, having birefringence, adhere to each other. The birefringence directions of the polymer films are parallel or orthogonal to the liquid crystal orientation direction. Since the compensating panel does not include glass substrates but includes polymer films, the display device can be thin and light.
