Abstract: An organic light emitting display apparatus wherein a shift of white light caused by a viewing angle is reduced by adjusting an offset distance between one end of a corresponding emission region and one end of the black matrix adjacent to the one end of the corresponding emission region, thereby preventing a white color shift phenomenon at various viewing angles. Accordingly, a certain image is produced regardless of a use environment of a user's viewing angle.
