Abstract:
1. A method of manufacturing an organic light-emitting display device, the method comprising: (a) sequentially forming a pixel electrode layer and a photo-sensitive organic film; (b) preparing a mask comprising a first transmission portion, a second transmission portion, and a third transmission portion which have different light transmission rates from each other; (c) positioning the mask on the photo-sensitive organic film such that the first transmission portion corresponds to a portion of the pixel electrode layer that is to be a pixel electrode, the second transmission portion corresponds to a portion of the pixel electrode layer that is to be removed, and the third transmission portion corresponds to a portion of the photo-sensitive organic film that is to be a pixel defining layer at an edge of the pixel electrode; (d) selectively exposing and removing the photo-sensitive organic film such that the pixel electrode layer is exposed and the portion of the photo-sensitive organic film that is to be the pixel defining layer remains; and (e) thermally reflowing a remaining portion of the photo-sensitive organic film that is to be the pixel defining layer such that the photo-sensitive organic film reflows to cover the edge of the pixel electrode.
