Abstract

An organic light-emitting diode (OLED) panel is provided. The OLED panel includes: a substrate having a light emitting region and a non-light emitting region; and an organic flat layer, an anode, a first pixel definition layer, a light emitting layer, a cathode and an encapsulation layer stacked on the substrate. On the non-light emitting region, a second pixel definition layer is further disposed between the first pixel definition layer and the encapsulation layer, and is disposed adjacent to a cutting location of the OLED panellight emitting layer; and the second pixel definition layer is constructed as inverted trapezoidal structures spaced apart from each other.
