摘要： Disclosed is a full color flat display panel by using an organic electro-luminescent(EL) device, a manufacturing method thereof and a driving circuit of the organic EL device, in particular, which includes first, second and third pixels, a plurality of first electrodes, and a plurality of second electrodes perpendicularly intersecting the first electrodes, in which each of the first, second and third light emitting pixels is arranged in each of intersecting positions of the first and second electrodes. Light emitting pixels are arranged to have different areas according to luminous efficiency so that a red light emitting area with relatively poorer efficiency is sized larger than a blue or green light emitting area thereby manufacturing an efficient full color organic EL display panel. Also, the influence from the line resistance in the anode lines and the cathode lines is reduced when a constant current is introduced into the device structured of the RGB array in order to realize the white light as full color. Thus, the voltage loss on the line resistance is prevented and the area ratio of the device is adjusted to make each of the RGB pixels for generating the white light have the similar value of drive voltage thereby minimizing power loss.

摘要： The present invention relates to a light emitting display device, such as an organic electroluminescent device, and a method for manufacturing the same. Particularly, the present invention relates to reducing electrical resistance between the scan lines and the cathode electrode layers so that scan line signals do not degrade significantly degrade. One way to achieve this is to use materials to form the conducting layers of the scan line and the cathode electrode layers such that the conductivities of the conducting layers and the cathode electrode layer are as identical as possible. For example, if a same metal such as aluminum is used to form both the conducting layer and the cathode electrode layer, the resistance would be significantly lowered. In addition, a large contacting area may be provided.
