Abstract: The present invention provides a display panel and a manufacturing method of the display panel. In the present invention, an adjustment structure is arranged on the light-emitting layer, and black photosensitive particles are arranged in the adjustment structure. When the display panel is in a bright state, light emitted by the light-emitting unit illuminates the black photosensitive particles, and the black photosensitive particles move toward positions corresponding to first gaps. Therefore, brightness at the light-emitting units is increased, and brightness at the first gaps is decreased. Accordingly, a contrast ratio of the display panel is increased.
