Abstract

The present invention discloses a display device and a method for repairing the same. The display device has a first substrate including lower electrodes, an upper electrode and a light-emitting layer disposed between the lower electrodes and the upper electrode; a second substrate which is combined with the first substrate and includes a color filter layer overlapping the light-emitting areas; a light-blocking member that overlaps a light-blocking area surrounding the light-emitting areas. The light-blocking member includes openings overlapping the lower electrodes.

Description

technical field [0001] The present invention relates to a display device, and more specifically, to a display device and a repair method for the display device. Background technique [0002] An organic light emitting display device, as a display device capable of emitting light by itself, can generate a color image without an additional light source such as a backlight. [0003] Recently, organic light emitting display devices including a color conversion layer are being researched in order to improve display quality. The color conversion layer may convert the wavelength of light provided from the light emitting element. Therefore, light having a color different from that of incident light can be emitted. For example, the color converting layer may comprise wavelength converting particles such as quantum dots. [0004] When defective pixels are generated due to inflow of impurities or the like during the manufacturing process of the organic light emitting display device, ...
