Manufacturing method for display device

An EL display device includes a TFT substrate on which a scanning line extends in a first direction, a video signal line extends in a second direction, and an EL element having an anode, a luminous layer and a cathode. A protective film covers the scanning line, the video signal line and the EL element. A touch panel detection electrode is disposed above the protective film, and connected to a wiring which is disposed under the protective film via a through hole of the protective film. The touch panel detection electrode has an angle to intersect with the video signal line.

The organic EL display device includes a TFT substrate on which a scanning line extends in a first direction, a video signal line extends in a second direction, and a pixel having an anode, an organic EL layer, and a cathode is formed on a region enclosed with the scanning line and the video signal line. A first detection electrode extends in the first direction above the pixel via insulation films. A counter substrate is disposed while covering the first detection electrode via an adhesive. A second detection electrode extends in the second direction at the outer side of the counter substrate.

An organic EL display device has a semiconductor circuit substrate comprising a TFT and an organic passivation layer thereon. An AlO layer is formed over the organic passivation layer, and an electrode layer is formed on the AlO layer. The electrode layer connects with TFT via a through hole formed in the AlO layer and in the organic passivation layer.

Semiconductor circuit substrate and display device using the same

The invention provides an organic EL display device that, even if bent, is not prone to plastic deformation and has improved moisture blocking characteristics. An organic EL display device includes: a glass substrate; an organic EL layer formed on an upper side of the glass substrate; and a support substrate glued on a lower side of the glass substrate via a first adhesive. Recessed portions or projecting portions are formed on the glass substrate at a side thereof facing the support substrate. The recessed portions or a space between each of the projecting portions is filled with the first adhesive.

Organic EL display device and liquid crystal display device

A sealing substrate is arranged to oppositely face an element substrate on which organic EL layers are formed in a matrix array with a sealing material sandwiched therebetween. A gel-state desiccant is filled in an inner space surrounded by the element substrate, the sealing substrate and the sealing material. Since the gel-state desiccant is in a gel state, the gel-state desiccant is flexibly filled in the inner space of the organic EL display device thus completely eliminating a gap. Since the inner space is filled with the gel-state desiccant, moisture hardly intrudes into the inner space from the outside and, at the same time, a mechanical strength of the organic EL display device is also enhanced.

An organic EL display device has a TFT formed on the substrate, and an organic EL layer formed on the TFT. A protective layer is formed on the organic EL layer, and a first barrier layer which contains AlOx is formed between the substrate and the TFT.
