    • Provided is an organic electro-luminescent display (OELD). The OELD includes: a plurality of unit pixels having an organic light emitting unit and a driving unit for driving the organic light emitting unit; and a substrate supporting the unit pixels, wherein the substrate has a non-planar portion corresponding to the light emitting unit and increasing a surface area, and the light emitting unit has a non-planar cross-sectional shape corresponding to the non-planar portion. The OELD has a concave portion or a convex portion for enlarging a surface such that the substantial area of an organic light emitting material increases. Thus, an effective light emission area increases in a pixel having a limited area and light emission of desired high brightness can be performed by a low driving voltage. A reduction in a driving voltage causes improvement in the durability of a pixel and the life span of the OELD is enlarged.
    • 提供有机电致发光显示器(OELD)。 OELD包括:具有有机发光单元的多个单位像素和用于驱动有机发光单元的驱动单元; 以及支撑单元像素的基板,其中所述基板具有对应于所述发光单元的非平面部分并增加表面积,并且所述发光单元具有对应于所述非平面部分的非平面横截面形状 。 OELD具有用于扩大表面的凹部或凸部,使得有机发光材料的实质面积增加。 因此,在具有有限面积的像素中有效发光面积增加,并且可以通过低驱动电压来执行期望的高亮度的发光。 驱动电压的降低导致像素的耐久性提高,并且扩大了OELD的寿命。
