Abstract: An electroluminescent display includes a lower substrate having a display area with subpixel emission areas defined in the display area; an electrode layer on the lower substrate; a planarization layer formed on the lower substrate such that holes are formed in the planarization layer with each hole being adjacent to a respective one of the subpixel emission areas; lower electrode layer in the respective subpixel emission area; a sacrificial layer surrounding the subpixel emission area and absent at an area having the lower electrode layer; an organic emission layer on the lower electrode layer; and an upper electrode layer on the organic emission layer.

Abstract: The present disclosure provides a light-emitting display device including a lower substrate, a transistor, a planarization layer, a sacrificial layer, an isolation layer, a lower electrode layer, an organic emission layer and an upper electrode layer. The isolation layer is positioned on the sacrificial layer, and exposes part of the planarization layer through an opening that extends through the isolation layer and the sacrificial layer. The planarization layer includes a first contact hole positioned in the opening, and the lower electrode layer is electrically connected to one electrode of the transistor through the first contact hole.

Abstract: Discussed is a color filter substrate and a display device having the same. The color filter substrate prevents color filter layers or color patterns from being lost or broken during a production process. The color filter substrate is formed by forming connection patterns in the edges of red (R), blue (B), and green (G) color filter layers and red (R), blue (B), and green G) color patterns. The connection patterns and color patterns are simultaneously formed with the color filter layers.
