Abstract: A pixel defining structure includes a first sub-pixel defining structure surrounding a first sub-pixel region configured to form a first sub-pixel having a first color. The first sub-pixel defining structure includes a lyophilic portion one the bottom side of the first sub-pixel region and a lyophobic portion on a side opposite to the bottom side. The pixel defining structure includes a second sub-pixel defining structure surrounding a second sub-pixel region configured to form a second sub-pixel having a second color. The second sub-pixel defining structure includes a lyophilic portion one the bottom side of the second sub-pixel region and a lyophobic portion on a side opposite to the bottom side. The second color is different from the first color. Thicknesses of the lyophilic portion of the first sub-pixel defining structure and the lyophilic portion of the second sub-pixel defining structure are different.
