Abstract

The embodiment of the invention discloses a display panel and a preparation method thereof, the display panel comprises a substrate and pixel units arranged on the substrate in an array mode, and each pixel unit comprises a first light-emitting subunit and a second light-emitting subunit; the first light-emitting subunit comprises a first light-emitting electrode, and the second light-emitting subunit comprises a second light-emitting electrode; and an electrode flat layer is arranged on the first light-emitting electrode, and the second light-emitting electrode is arranged on the electrode flat layer. A multi-layer flat layer structure of the display area is utilized, the first light-emitting electrode in the first light-emitting subunit and the second light-emitting electrode in the second light-emitting subunit are arranged on different flat layers, and the brightness attenuation difference caused by view angle increase is relieved by reducing the emergent angles of light rays of different colors, so that the color cast of the white light along with the view angle change is relieved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Organic light-emitting display panels have been gradually recognized by the market due to their advantages such as self-illumination, high contrast, wide color gamut, and low power consumption. However, the red light, green light and blue light emitted by the red sub-pixel, green sub-pixel and blue sub-pixel have different luminance attenuation curves with the increase of the viewing angle, which results in a color shift of the white light as the viewing angle changes. Contents of the invention [0003] Embodiments of the present application provide a display panel and a manufacturing method thereof, which solves the technical problem of color shift in the display panel as the viewing angle changes in the prior art. [0004] An embodiment of the present application provides a display p...
