摘要： In an organic light emitting display device, a plurality of pixel regions are formed two-dimensionally on a transparent substrate, wherein each pixel region includes the multilayered structure which is formed by sequentially stacking a lower transparent electrode, an organic light emitting layer (including at least one organic material layer) and an upper reflection electrode from the transparent substrate side. In such a constitution, at least one concavity which forms a recessed surface with respect to the transparent substrate is formed in the multilayered structure of each pixel region, thus enlarging the effective area of a light emitting portion so as to provide an image display of high brightness with a low current. The concavities are, for example, formed by a plurality of projecting portions on the transparent substrates and by covering the projecting portions with the multilayered structure.

摘要： A method and apparatus for correcting transparent defects on a photomask are disclosed. A metal-organic complex solution is applied to a transparent defect portion and its periphery on the photomask. The transparent defect portion is then exposed to a visible ray or ultraviolet ray to deposit a metal, a metal oxide or a composition thereof, while the light transmission quantity through the transparent defect portion is measured. After the measurement falls below a predetermined level relative to the quantity of the transmitted light at the start of exposure, the exposure is terminated to thereby complete the correction of the transparent defects.
