Abstract

The present invention provides a display panel and a manufacturing method thereof. The display panel includes a substrate, a plurality of active switches, a passivation layer, a pixel definition layer, a planarization layer, a color resistance layer and a transparent electrode layer; the plurality of active switches are disposed on the substrate; the passivation layer is disposed on the substrate and covers the active switches; the pixel definition layer is disposed on the passivation layer and is provided with a plurality of light-emitting elements; the planarization layer is disposed between the passivation layer and the pixel definition layer; a groove structure is formed in the planarization layer; the color resistance layer is disposed between the passivation layer and the planarization layer and is aligned with the groove structure of the planarization layer; and the transparent electrode layer is disposed on the planarization layer and covers the groove structure; and the light-emitting elements are disposed in the groove structure of the planarization layer and are aligned with the color resistance layer. With the manufacturing method thereof of the present invention adopted, the light-emitting efficiency of a self-luminous panel can be improved, the manufacturing process and yield of the panel can be optimized, and the color cast phenomena of the self-luminous display panel can be decreased.

Description

technical field [0001] The present application relates to a display panel and a manufacturing method thereof, in particular to a light emitting diode display panel and a manufacturing method thereof. Background technique [0002] At present, high-pixel flat display panels are the market trend, and AMOLED (Active Matrix / Organic Light Emitting Diode, active matrix organic light-emitting diode) panels have attracted everyone's attention, and AMOLED panels are in the small and medium-sized panel market with 200ppi pixels. Occupying a dominant position, AMOLED WVGA (Wide Video Graphics Array, a resolution higher than VGA resolution: 800*480; ~200ppi) is the current mainstream resolution, while high-pixel 250ppi, 300ppi and 350ppi will be the future development trend. The existing AMOLED panel production method is mainly based on Side by Side (side by side) technology, but the technology has certain difficulties in producing products with 300ppi and above. Therefore, the industr...
