DISPLAY PANEL, ITS DRIVING METHOD AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To suppress voltage-drop/signal-delay without damaging display properties. SOLUTION: An EL display panel 1 is equipped with: an insulating substrate 2; driving transistors 23 arranged in a matrix on the insulating substrate 2; signal lines Y1to Ynpatterned with a gate 23g of the driving transistor 23 and arranged parallel to one another; a protective insulating film 32 covering the signal lines Y1to Ynand the driving transistors 23; a pixel electrode 20a electrically connected to the drain 23d of each driving transistor 23; an organic EL layer 20b formed on each pixel electrode 20a; a counter electrode 20c covering the organic EL layer 20b; and a feeder line 90 formed on the protective insulating film 32 to be parallel to the signal lines Y1to Ynbetween adjacent pixel electrodes 20a, and connected to the source 23s of the driving transistor 23 through a contact hole 53 formed in the protective insulating film 32.
