ABSTRACT:
A method for making a light-emitting display device having a substrate with light-emitting layers on a surface of the substrate and constituting pixels, light emission from the pixels being electrically controlled, and having barriers delimiting at least one side of each respective pixel. A mask pattern is formed on a surface of the substrate, corresponding to the pattern of the barriers to be formed, and the surface is sprayed with sandblasting particles to form grooves having a depth corresponding to a height of the barriers and irregularities producing light scattering on the side walls and bottoms of the grooves, a difference between a maximum height and a minimum height of the irregularities being at least 0.4 mm.
