Patent ID: 7256757

Claim:
An organic EL display panel comprising: a substrate; pixel electrodes which are arranged in a matrix form on the substrate; a common electrode which faces the pixel electrodes; signal lines which extend along a vertical direction and are arranged in a gate line direction at a predetermined interval; power supply lines which extend along the vertical direction and are arranged in the gate line direction at a predetermined interval; scan lines which extend along the gate line direction and are arranged in the vertical direction at a predetermined interval; organic EL elements which are arranged between the pixel electrodes and the common electrode and each of which emits light when a current flows between the pixel electrode and the common electrode; first thin-film transistors each of which is connected between the power supply line and the pixel electrode; storage capacitors each of which includes a first electrode connected to a gate of the first thin-film transistor; and second thin-film transistors each of which is connected between the signal line and the gate of the first thin-film transistor, wherein, to obtain a full color image by light emissions of the organic EL elements, a red (R) emitter, a green (G) emitter and a blue (B) emitter are patterned correspondently with the pixel electrodes and arranged in this order along the gate line direction, wherein the emitters are patterned such that each pair of the red (R) emitter, the green (G) emitter and the blue (B) emitter which are adjacent to each other along the gate line direction overlap each other to define a light-emitting layer overlap region, where colors of light components which exit the organic EL elements and pass through the emitters are mixed, between the adjacent organic EL elements arranged along the gate line direction, and wherein at least one of the first thin-film transistor, the second thin film transistor and the storage capacitor is placed in the light-emitting layer overlap region.
