Abstract

The invention provides a transistor with a reduced characteristic deviation. An electric field shielding electrode (54) is disposed between a BL insulating film (53) of a transistor and a BL insulating film (55), and a barrier film (58) is composed of the three layers. The electric field shielding electrode (54) shields the electric field of a drain electrode (T1d), a source electrode (T1s) and a n+-Si film (56). Therefore, in various driven transistors, even if the alignment dislocation of the drain electrode (T1d), the source electrode (T1s) and the n+-Si film (56) is deviated and the overlapping part with an i-Si film (52) is enlarged, the electric field of the part is shielded by the electric field shielding electrode (54), and the characteristic deviation is reduced.

Description

technical field [0001] The present invention relates to transistors, display devices, electronic equipment and methods for manufacturing transistors. Background technique [0002] In recent years, as a next-generation display device following the liquid crystal display device (LCD), a display panel equipped with a light-emitting element type in which self-emitting elements such as organic electroluminescence elements (hereinafter referred to simply as "organic EL elements") are two-dimensionally arranged Research and development of display devices (see Patent Document 1, Japanese Laid-Open Patent Publication, Japanese Patent Application Laid-Open No. 08-330600). [0003] An organic EL element includes an anode electrode, a cathode electrode, and an organic EL layer (light-emitting functional layer) having, for example, a light-emitting layer, a hole injection layer, and the like formed between the pair of electrodes. An organic EL element emits light using energy generated ...
