Abstract

Disclosed is a display apparatus. The display apparatus includes a display region. The display region includes a shift linear-variation region and a shift non-linear-variation region. In the shift linear-variation region, shifts vary linearly with image heights of pixel units along the first direction. In the shift non-linear-variation region, shifts vary non-linearly with image heights of pixel units along the first direction. Further disclosed is a near-eye display device.
