Abstract
(EN)
Provided is a display panel, which comprises a display region and a bent region. The display panel comprises a flexible substrate; an etching stop layer arranged on the flexible substrate; an inorganic material functional layer arranged on the etching stop layer, wherein the flexible substrate, the etching stop layer and the inorganic material functional layer comprise the display region and the bent region; a flat layer arranged on the inorganic material functional layer; and an anode and a pixel definition layer, which are formed on the flat layer in sequence. The bent region comprises a groove arranged on the etching stop layer; the groove penetrates the inorganic material functional layer through etching; the groove is filled with a polymer material; and the bent region is connected to the display region via a signal line.
