The method for manufacturing a display device includes forming a light emitting element and a terminal on a substrate, forming a sealing film including a first inorganic insulating film and a second inorganic insulating film to cover the light emitting element and the terminal, forming a resist having a taper shape in which a thickness of an end portion on the sealing film becomes thinner as it goes to the terminal side by using a gray-tone mask, forming a taper shape in which thicknesses in end portions of the first inorganic insulating film and the second inorganic insulating film becomes thinner as it goes to the terminal side by etching, forming a touch electrode above the sealing film and forming wiring connected to the terminal via the end portions together with connecting to the touch electrode for detecting a touched position.

Sensor device

A sealing member containing conductive particles and disposed in a seal region is formed between a display panel and a touch panel. A laminated structure formed on the display panel includes a first detection lines. The first detection lines extend from the seal region to a connection region and are connected through the conductive particles to terminals of second detection lines formed on the touch panel. A peripheral edge of the organic barrier is located inward from the conductive particles of the sealing member. The above described structure can facilitate a work for connecting external lines such as FPC to the display panel and the touch panel. Further, the structure can secure stability of electrical connection between the external lines and the touch panel.

Semiconductor device including detection electrodes applicable for a touch sensor

The touch sensor includes a touch detection area with at least a part of a curved area having a curved edge. In the touch detection area, a plurality of first electrodes and second electrodes disposed side by side in a first direction and in a second direction are disposed. A plurality of first electrodes disposed side by side in the first direction are connected to each other. A plurality of second electrodes disposed side by side in the second direction are connected to each other. In the curved area, distances between the plurality of first electrodes and the second electrodes in the first direction gradually change in the second direction.

Display device

The display device includes a substrate, a display region arranged on the substrate and including a plurality of pixels, a first wiring provided on the substrate, an insulating layer overlapping a portion of the first wiring, an oxide conductive layer provided on the first wiring and electrically connected to the first wiring, a sealing layer overlapping the display region and at least an end of the oxide conductive layer and sealing the plurality of pixels, a sensor electrode provided on the sealing layer and overlapping the display region, and a second wiring passing over the at least end of the oxide conductive layer provided with the sealing layer and electrically connecting the sensor electrode and the oxide conductive layer.

Display device and method of manufacturing display device

The first and second touch electrodes constitute a mesh shape of staying away from overlap with the light-emitting pixels. Each electrode body has a first slim portion between adjacent light-emitting pixels in the first direction. Each electrode body has a first wide portion between adjacent light-emitting pixels in the second direction. The first wide portion is wider than the first slim portion. The jumper electrode has a second slim portion between adjacent light-emitting pixels in the first direction. The jumper electrode has a second wide portion between adjacent light-emitting pixels in the second direction. The second wide portion is wider than the second slim portion. The light-emitting pixels each have a planar shape longer in the second direction than in the first direction. The first and second wide portions are overlapped and electrically conductive, penetrating the insulation film.

Display device including wirings electrically connecting oxide conductive layer and sensor electrode

A display device has a first electrode provided corresponding to each of a plurality of pixels in a region in which the plurality of pixels is provided, a second electrode provided over the plurality of pixels and extending to a contact region provided outside the pixel region, a light emitting layer provided between the first electrode and the second electrode, a third electrode provided in the contact region, an organic insulating layer covering the third electrode and provided with a contact hole exposing the third electrode, and a connection portion between the second electrode and the third electrode in the contact hole, wherein the maximum distance between any two points on the outer periphery of the connection portion is 1 &#x3bc;m or more and 100 &#x3bc;m or less.

Substrate

First electrodes are formed on an insulation surface in such a manner that the adjacent first electrodes are connected in a first direction and are separated in a second direction intersecting the first direction. Second electrodes are formed on an insulation surface in such a manner that the adjacent second electrodes are connected in the second direction and are separated in the first direction. Third electrodes are formed in regions in which the third electrodes overlap with the first electrodes and do not overlap with the second electrodes in such a manner that the adjacent third electrodes are connected in the second direction and are separated in the first direction. A flexible insulation layer is formed between the first electrodes and the third electrodes. An area of each of the third electrodes is less than an area of each of the first electrodes.
