Abstract
The present invention provides a display panel, a display device, and a manufacturing method of a display panel. A side wall of a black matrix unit is arranged at an inclined angle, so light is more easily emitted from a black matrix, and a light emission angle is increased. Accordingly, a light transmittance and a viewing angle of an organic light-emitting diode (OLED) are increased. Therefore, the display performance of the OLED is effectively improved.
