Publication number: 20230295791Abstract: The present application provides a mask assembly and an evaporation device to effectively reduce a possibility that wrinkles are generated in a first mask and effectively avoid edge color mixing. The mask assembly includes a frame, and a first mask and a second mask stacked on the frame. The first mask includes a plurality of mask strips disposed along a first direction, and a gap is disposed between two adjacent mask strips. The second mask includes a body and support strips. The support strips include a plurality of first support strips disposed along the first direction and a plurality of second support strips disposed along a second direction. Widths of first ends of outermost first support strips and first ends of outermost second support strips gradually increase along a direction from being away from the body to being close to the body, and the first support strips are disposed corresponding to the gaps. The evaporation device includes the mask assembly.Type: ApplicationFiled: October 28, 2021Publication date: September 21, 2023Inventors: Jiangtao DENG, Peng XU
