Abstract: In a light emitting display device, a light blocking member is positioned on an encapsulation layer and includes a red opening, a blue opening, and a green opening. The red opening, the blue opening, and the green opening have a mass center, a first position closest to the mass center, and a second position furthest from the mass center. In case that a ratio of a distance from the mass center to the second position to a distance from the mass center to the first position is referred to as a maximum minimum distance ratio, the red opening has a value of about 1.02 or more and about 1.15 or less, the blue opening has a value of about 1.05 or more and about 1.2 or less, and the green opening has a value of about 1.32 or more and about 1.38.
