A display device includes a first substrate, a second substrate, a first polarizer, a second polarizer and a frame. The frame contacts with a first surface and a first side of the first substrate, a second surface and a second side of the second substrate, and a third side of the first polarizer. The frame has a fourth surface and a fourth side connecting to the fourth surface, and the fourth side is disposed corresponding to the second side. In a first direction perpendicular to the first surface, a shortest distance between the fourth and first surfaces is a first distance, a shortest distance between the fourth and first surfaces is a second distance, and a shortest distance between the third and first surfaces is a third distance. The third distance is substantially equal to the first distance, and the first distance and the second distance are different.
