Abstract: A display device includes a light emitting layer and color filter arrays. The color filter arrays comprise a first color filter array of a first color, and a second color filter array of a second color. The first color filter array comprises a first pair of color filters adjacent to each other with a first clearance therebetween and a second pair of color filters adjacent to each other with a second clearance therebetween. The second color filter array comprises a first color filter positioned between the first pair of color filters and a second color filter positioned between the second pair of color filters. A width of the first clearance is larger than a width of the second clearance. A width of the first color filter is larger than a width of the second color filter. The second color filter partially overlaps with the second pair of color filters.
