Abstract

Thin-film transistor elements are formed inside first and second openings constituted by partition wall enclosures. A third opening is disposed on the partition wall, adjacent to the first opening with a space therebetween, on the side that differs to the side on which the second opening is adjacent. In a plan view of the bottom of the first opening, the center position of the surface area of a lyophilic layer inside the first opening is further toward the side that differs to the side on which the third opening is adjacent than the center position of the area at the bottom. Furthermore, in a plan view of the bottom of the first opening and the bottom of the second opening, in either the first opening or the second opening, the center position of the surface area of the lyophilic layer of the bottom thereof is further toward the side that differs to the side on which the other opening is adjacent than the center position of the area at the bottom of said opening.

Description

technical field [0001] The invention relates to a thin film transistor device and its manufacturing method, an organic EL display element and an organic EL display device. Background technique [0002] In liquid crystal display panels and organic EL display panels, thin film transistor devices (devices) in which thin film transistor (TFT (Thin Film Transistor)) elements are formed for each sub-pixel are used in order to control light emission on a sub-pixel basis. And, especially, the development of thin film transistor devices using organic semiconductor materials as semiconductor layers has been progressing.
