Patent ID: 8293570

Claim:
A method for manufacturing a light emitting device, comprising: providing a substrate, the substrate including a plurality of pixel areas, each of the pixel areas including a plurality of first sub-pixel areas arranged in row, a plurality of second sub-pixel areas arranged in row, and a plurality of third sub-pixel areas arranged in row; providing a mask on the substrate, the mask including a plurality of sub-mask units and a gap formed between each two adjacent sub-mask units, each of the sub-mask units including a main body with a plurality of openings, the main body shielding the second sub-pixel areas and the third sub-pixel areas, the openings arranged in row, each opening exposing one first sub-pixel area corresponding to the opening, each gap exposing a plurality of first sub-pixel areas in a same row corresponding the gap, and the width of each gap being at least larger than 25 um; and through the mask, forming a first structure layer in each first sub-pixel area corresponding to one opening, and forming a first common structure layer in each plurality of first sub-pixel areas in a same row corresponding to one gap, and the first structure layer and the first common structure layer commonly acting as an organic functional layer or an electrode layer.
