Embodiment 1

[0082] FIG. 2 is a plan view showing the display portion 10 of the top emission organic electroluminescent display device according to the first embodiment. The TFT formation region PTr of a plurality of display pixels P, that is, the formation region of the driving TFT 61A, the pixel selection TFT 71A, and the storage capacitor Cs is formed in a rectangular shape and arranged in stripes on the display portion 10 . Here, the light-emitting regions r1 , g1 , and b1 of the organic electroluminescent element 11A constituting each display pixel P are formed in a rectangular shape at equal intervals and arranged in a triangular shape across the adjacent TFT formation region PTr.

[0083] FIG. 3 is a plan view showing the display portion 10 of the top emission organic electroluminescent display device according to the second embodiment. The plurality of TFT formation regions PTr are formed in a rectangular shape, are arranged offset in the column direction, and are arranged in a tri...

Abstract

In an organic EL display device, emissive regions are arrayed in various patterns without depending on array patterns of the TFT formation regions and so on. A plurality of TFT formation regions PTr of pixels P is formed in a stripe array on a display portion. Emissive regions R 1 of the organic EL element 11 A emitting red light, emissive regions G 1 of the organic EL element 11 A emitting green light, and emissive regions B 1 of the organic EL element 11 A emitting blue light are arrayed on these TFT formation regions PTr. The emissive regions R 1 , G 1 , and B 1 are disposed in delta array over the adjacent TFT formation regions PTr.

Description

technical field [0001] The present invention relates to an organic electroluminescence (ectro Luminescence; electroluminescence) display device, in particular to an organic electroluminescence display device that improves the degree of freedom in the arrangement position of a light emitting region of an organic electroluminescence component. Background technique [0002] In recent years, organic electroluminescence display devices using electroluminescence (ectro Luminescence) components are attracting attention as display devices replacing CRTs and LCDs. In particular, an organic electroluminescent display device having a thin film transistor (Thin Film Transistor: hereinafter referred to as TFT) as a switch element for driving the organic electroluminescent element has also been developed. [0003] Organic electroluminescent display devices generally have bottom emission (Bottom emission) type and top emission (Top emission) type. Hereinafter, a bottom emission type organ...
