An organic light emitting display device (300) includes a plurality of pixels defined on a substrate. Each of the plurality of pixels includes a plurality of sub-pixels (SP_R, SP_W, SP_B, SP_G), and each of the plurality of sub-pixels includes a light emitting area (EA_R, EA_W, EA_B, EA_G) and a driving area (DA_R, DA_W, DA_B, DA_G). The driving areas of the plurality of sub-pixels have widths in a first direction (S1, S2, S3, S4), and the widths in the first direction of the respective driving areas of the plurality of sub-pixels are identical to each other. A size of a light emitting area of one of the plurality of sub-pixels (331W or 331B) is greater than a size of a light emitting area of one of other sub-pixels (331R or 331G). In the organic light emitting display device according to an aspect of the present invention, while the widths in the first direction of the respective driving areas of the plurality of sub-pixels are maintained as being identical to each other, a size of a light emitting area of each of the plurality of sub-pixels can be optimized by changing sizes of the light emitting areas of the plurality of sub-pixels without making a change in the size of a pixel and a size of a driving area. Thus, reliability and life of the organic light emitting display device can be improved. |
