A light-emitting display device includes a substrate and light-emitting layers
constituting pixels on a surface of the substrate in which light emission is electrically
controlled for every pixel. The light-emitting display device further includes
barriers delimiting at least one side of each pixel. On the surface of the substrate,
at least part of a region that corresponds to each pixel has irregularities for
light scattering. The difference between the maximum height and the minimum height
of the irregularities is at least 0.4 m. The barriers and the irregularities
are formed by sandblasting the surface of the substrate. The irregularities reduce
attenuation of light by total reflection in the interior of the substrate and improve
brightness of the device.
