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.

Method for forming color filter array and method for manufacturing electronic device

A method for forming a color filter array includes the step of forming a first color filter array by forming a first color filter film on a surface of a base member using a coating method and by patterning the first color filter film and the step of forming a second color filter array by forming a second color filter film on the surface so as to cover the first color filter array using a coating method and by patterning the second color filter film. The color filters in the first color filter array are uneven in the width of the clearance between the color filters and/or the widths of the color filters.
