Abstract

The present application discloses a dual-cell display device. The dual-cell display device includes: a first backplane, a first panel, and a second panel arranged in order along a thickness direction of the dual-cell display device, where the first panel includes at least one first flexible circuit board on a side of the first panel; and the second panel includes at least one second flexible circuit board on a counterpart side of the second panel corresponding to the side of the first panel where the at least one first flexible circuit board is disposed. The dual-cell display device further includes: a first drive board and a second drive board which are arranged in parallel on the first backplane; and a distance between the first drive board and the first backplane is different from a distance between the second drive board and the first backplane.
