Patent ID: 7498733

Claim:
A display panel comprising: a transistor array substrate which comprises a plurality of transistors, including driving transistors; a plurality of pixel electrodes which are electrically connected to said plurality of driving transistors, said plurality of pixel electrodes being provided by patterning a transparent conductive film; a plurality of light-emitting layers provided the pixel electrodes; a counter electrode which is provided on the light-emitting layers; a plurality of common interconnections, each of which is arranged between adjacent pixel electrodes and electrically connected to the counter electrode; an insulating film provided on the transistors; a plurality of feed interconnections, each of which is provided in a trench formed in the insulation film; and a portion of said transparent conductive film, which has been patterned to provide the pixel electrodes, mounted on each of the feed interconnections; wherein the pixel electrodes, the light emitting layers, and the counter electrode form a plurality of light emitting elements; wherein the light emitting elements and the driving transistors respectively connected thereto are connected in series; and wherein each pair of one of the light emitting elements and one of the driving transistors has a first end connected to one of the common interconnections, and a second end connected to one of the feed interconnections.
