Example Embodiment
[0034] In order to make the technical problems, technical solutions, and advantages to be solved by the embodiments of the present invention clearer, a detailed description will be given below with reference to the drawings and specific embodiments.
[0035] In the manufacturing process of OLED display devices, after depositing the passivation layer, a flat layer needs to be deposited. The flat layer can be made of photosensitive acrylic material, and the flat layer is exposed and developed to form the first via hole penetrating the flat layer; A photoresist is formed on the photoresist, and the photoresist is exposed and developed to form a photoresist pattern. Using the photoresist pattern as a mask, the passivation layer is etched, and a dry etching process is used to form the first passivation layer. Two vias. The depth of the second via hole is relatively large. The slope angle of the second via hole formed after the dry etching process is generally 80-90°. When ITO is subse...
