Abstract: A light emitting display device comprises a substrate, a first pixel electrode disposed on the substrate, a pixel defining film disposed on the first pixel electrode and having a first opening at least partially exposing the first pixel electrode, a first organic light emitting layer disposed on the pixel defining film and overlapping with the first opening of the pixel defining film, and a black matrix disposed on the first organic light emitting layer and having a first opening overlapping with the first organic light emitting layer. Light having passed through the first opening of the black matrix is one of red light, green light, and blue light. The first opening of the black matrix may have a shape with a curved portion.

Abstract: A manufacturing method of a liquid crystal display includes forming display pixels which display an image and dummy pixels which do not display the image on a lower substrate including a display area and a non-display area positioned in at least one side outside the display area, coating a light blocking member material layer on a first dead space area adjacent to the display area and having a dummy area where the dummy pixels are positioned, a second dead space area adjacent to the first dead space area, and a third dead space area adjacent to the second dead space area in the non-display area, and forming first to third light blocking members through exposure by using an optical mask in which at least two or more halftone regions and a full-tone region are mixed.

Abstract: A liquid crystal display device includes: a first substrate on which a display area and a non-display area surrounding the display area are defined; a plurality of gate lines disposed in the display area and extending in a first direction; a plurality of data lines disposed in the display area and extending in a second direction, the data lines intersecting the gate lines; and a black matrix extending in the first line to cover the gate lines or in the second direction to cover the data lines, where a width of the black matrix at a location adjacent to a boundary line between the display area and the non-display area is larger than a width of the black matrix at a location adjacent to a center of the display area.
