Display panel and display apparatus
By introducing a flat portion in the photoresist unit, the photoresist portion that contacts the encapsulation layer is manufactured before other photoresist portions, thus solving the problem of poor leveling of the photoresist portion and improving the display effect and brightness uniformity of the display panel.

AI Technical Summary
Technical Problem
In display panels without polarizer technology, the photoresist layer of the color filter layer has poor leveling properties, resulting in a depression at the top and affecting the display effect.
Method used
A flat section is introduced in the photoresist unit, so that the photoresist section that contacts the encapsulation layer is fabricated before other photoresist sections, and other photoresist sections are set on the flat section to reduce the step difference between photoresist sections and ensure smooth leveling of photoresist sections.
Benefits of technology
The leveling of the photoresist layer is improved, preventing light convergence and enhancing the display effect and brightness uniformity of the display panel.
