ABSTRACT:
An organic electroluminescence (EL) display unit includes a plurality of pixels formed on a glass substrate and each including a TFT area and a luminescence area. An edge cover film covers the TFT area and exposes the luminescence area through a window formed in the edge cover film. The edge of the edge cover film adjacent to the window has a taper angle equal to or smaller than 30 degrees. This taper angle is obtained by a post-baking treatment in addition to a step alleviating film formed in the luminescence area to underlie the organic EL element.
