The invention discloses a display panel and a manufacturing method thereof. The display panel comprises a circuit substrate, a plurality of first electrodes, a first retaining wall layer, a second retaining wall layer, an organic light-emitting material layer and a second electrode. The first retaining wall layer is located on the first electrode and provided with a plurality of first openings overlapped on the first electrode. The second retaining wall layer is located on the first retaining wall layer and the circuit substrate. The second retaining wall layer is provided with a plurality of second openings extending in the first direction. The single second opening has a different width in the second direction. The second openings are overlapped with the first openings, and the second openings and the first openings jointly form a plurality of organic light-emitting material filling areas. The maximum width of the first part of each organic light-emitting material filling area is larger than the maximum width of the second part of each organic light-emitting material filling area.
Description
technical field [0001] The present invention relates to a display panel, and in particular to a display panel including an organic luminescent material and a manufacturing method thereof. Background technique [0002] Organic Light Emitting Diode (OLED) is a kind of electroluminescent semiconductor element, which has the advantages of high efficiency, long life, unbreakable, fast response, and high reliability. With the advancement of manufacturing technology, the size of organic light emitting diodes is gradually reduced, thereby obtaining a display device with higher resolution. However, in order to manufacture a display device with high resolution, the process precision of depositing the organic light-emitting material must be high enough, otherwise the organic light-emitting material may be formed in an unexpected area and affect the image quality of the display device. Contents of the invention [0003] The invention provides a display panel, which can improve the pr...
