Thin film transistor array substrate, light-emitting panel and manufacturing method thereof as well as electronic device

Abstract

The invention provides a thin film transistor array substrate, a light-emitting panel and a manufacturing method thereof as well as an electronic device. A thin film transistor array substrate includes a substrate, thin film transistors formed on the substrate, wirings provided on the substrate. The wirings are subjected to an application of a voltage to drive circuits including the thin film transistors. At least part of the surface of each of the wirings is made of an anodic oxide film.

Description

[0001] This application is based on Japanese Patent Application No. 2009-226156 filed on September 30, 2009, and the priority of this earlier application is claimed, and all the contents of this earlier application are incorporated in this application. technical field [0002] The invention relates to a thin film transistor array substrate, a light-emitting panel, a manufacturing method thereof, and electronic equipment. Background technique [0003] In recent years, as a display device of electronic equipment such as a mobile phone or a portable music player, a device using a display panel in which a light-emitting element such as an organic electroluminescent element (hereinafter, simply referred to as "organic EL element") is widely known Dimensionally arranged display panel (light-emitting element type display panel). In particular, in the light-emitting element type display panel to which the active matrix driving method is applied, compared with the widely used liquid ...

Problems solved by technology

[0007] However, the more film formation and patterning processes, the easier it is to generate particles (fine foreign matter) on the substrate, so the remaining particles short-circuit the positive electrode and the negative electrode, and point defects occur, reducing the manufacturing yield (increasing the defective rate).

That is, when comparing the liquid crystal element structure and the organic EL element structure, since the light-emitting functional layer in the organic EL element is much thinner than the liquid crystal layer in the liquid crystal element, the probability of occurrence of point defects in particles becomes high.

In addition, as mentioned above, when it is desired to increase the image quality of the display panel and increase the size of the screen, the influence of particles is relatively large.
