Abstract: A display panel producing frame-free image displays is provided. The display panel includes a display substrate (1) and an optical device (2) in a light illuminating side of the display substrate (1). The display substrate (1) includes frame edge regions (11) and a display region (12) abutting the frame edge regions (11). The display substrate (1) is curved at the frame edge regions (11). The optical device (2) is above the display region (12) and the frame edge regions (11), and changes a direction of light illuminated by the display substrate (1) such that images displayed through the display region produce a frame-free display.
