Embodiment Construction
[0036] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.
[0037] In the prior art, in the process of preparing the pixel defining layer using negative photoresist, such as Figure 1a As shown, a pixel-defining material layer 2 is formed on a substrate 1 , a mask 4 is arranged on the pixel-defining material layer 2 , and ultraviolet light 3 is irradiated to the pixel-defining material layer 2 from above the mask 4 . Such as Figure 1b Shown is the pixel defining layer 5 formed after exposure and development. The positive trapezoidal part in the figure is the pixel defining layer ...
