    Abstract: The invention prevents disconnection of data lines that traverse two-layered gate lines via an insulating film.Data lines 20 override and thereby traverse gate lines 10 with an insulating film deposited therebetween. The gate lines 10 each have a two-layered structure including a lower AlCu layer 11 and an upper MoCr layer 12. When the thickness ratio of the upper layer 12 to the lower layer 11 is in the range of 0.4 to 1.0, it is possible to prevent a decrease in the etch speed of the upper layer 12 near the side edges of the gate line 10, which occurs due to galvanization. As a result, the upper layer 12 is prevented from having an overhang. The absence of overhangs on the gate lines 10 prevents the data lines 20 from being disconnected at the intersections of the gate lines 10 and the data lines 20.

    Abstract: Separation of wirings formed on an organic passivation film is prevented in an organic EL display device or a liquid crystal display device. The organic EL display device includes a TFT formed on a substrate and an organic passivation film formed to cover the TFT. An intermediate film containing SiO or SiN is formed to cover the organic passivation film. An insulation film formed with an organic material is formed on the intermediate film. A reflective electrode is formed on the intermediate film. The reflective electrode is connected to the TFT via a through-hole formed in the organic passivation film and a through-hole formed in the intermediate film.

    Abstract: A space between a lower substrate and an upper substrate including an organic EL light-emitting layer which includes a display region for displaying an image is filled by a dam material which is applied to enclose an exterior edge of the display region and a filling material which is dripped into the interior side of the dam material. The dam material is an epoxy resin with a comparatively high viscosity before hardening and the filling material is an epoxy resin with a comparatively low viscosity before hardening. A substrate concave part is formed between the display region on a surface of the lower substrate and a coating region of the dam material.
