Disclosed is a display device possessing: a substrate having a display region and a peripheral region surrounding the display region; a pixel over the display region; a passivation film over the pixel; a resin layer over the passivation film; a first dam over the peripheral region and surrounding the display region; and a second dam surrounding the first dam. The passivation film includes; a first layer containing an inorganic compound; a second layer over the first layer, the second layer containing an organic compound; and a third layer over the second layer, the third layer containing an inorganic compound. The second layer is selectively arranged in a region surrounded by the first dam. The resin layer is selectively arranged in a region surrounded by the second dam.

Display device

Display device includes a flexible substrate, a plurality of pixels disposed on a first surface of flexible substrate, and a plurality of alignment marks disposed along one side of the flexible substrate and identified each other. The plurality of alignment marks may be arranged in the same layer. When the plurality of pixels includes thin film transistor, the plurality of alignment marks may be formed of the same metal layer as the metal layer forming thin film transistor.

Each of the first connection line and the second connection line includes a first layer wiring on a first layer and a second layer wiring on a second layer different from the first layer, the first layer wiring being disposed obliquely and rightward to an extending direction of the first connection line and the second connection line, the second layer wiring being disposed obliquely and leftward to the extending direction and connected to the first layer wiring. The first layer wiring of the first connection line and the second layer wiring of the second connection line are disposed to intersect each other.

A display device includes a substrate; a display portion located on the substrate, the display portion including a plurality of pixels; a first marker located in an end area that is along a longer side of the substrate and is in at least one of four corner areas of the substrate, the first marker extending in a longer axis direction of the substrate; and a second marker located in an end area that is along a shorter side of the substrate and is in the same corner area as that of the first marker, the second marker extending in a shorter axis direction of the substrate.

Display device and method for manufacturing the same

A display device includes first, second and third connection wiring. The second connection wiring is located in a same layer as the first connection wiring. The third connection wiring is located in a layer different from the first connection wiring. The first connection wiring includes at least one first region running in a first direction and at least one second region running in a second direction different from the first direction. The second connection wiring includes at least one third region running in the first direction and at least one fourth region running in the second direction.

The at least one first region, the at least one third region, and the at least one fifth region are adjacent to one another.

A touchscreen includes an OLED, upper-layer inorganic films on the OLED, a lower-layer inorganic film stacked between the OLED and a substrate, and a touch sensor on the upper-layer inorganic film. The upper-layer inorganic films and the lower-layer inorganic film extend over a display area and a picture-frame area. A lower-layer wiring is formed of a conductive film stacked between the OLED and the substrate. A sensor wiring is formed of a conductive film on the upper-layer inorganic film. An inorganic film joining portion where the upper-layer inorganic films and the lower-layer inorganic film are directly joined together or joined together with another inorganic material interposed therebetween is provided in the picture-frame area. A contact portion that electrically connects the sensor wiring with the lower-layer wiring is provided, in a plan view, in the inorganic film joining portion or an area on the outside thereof.

Touchscreen

A display device includes a low-definition display section and a high-definition display section. An area of pixels of the high-definition display section is smaller than an area of pixels of the low-definition display section. The position of the center of the high-definition display section is shifted from the position of the center of the display region. Consequently, when the display device is worn on the head of a user and disposed in front of the eyes, it is possible to provide a high-definition image. It is possible to reduce a processing load of moving image processing.

Display device and head mounted display device

Layers on a resin substrate in a peripheral area include wires extending in a wiring direction, and an inorganic insulating layer. The inorganic insulating layer is formed on first regions under the plurality of respective wires and on second regions each positioned between the adjacent first regions. The inorganic insulating layer includes a first portion on each first region. The inorganic insulating layer includes a second portion on each second region. The first portion is continuous in the wiring direction. The second portion is formed in at least either one of the manners such that the second portion is formed while avoiding a part of the second region on which the second portion is disposed or that the second portion is formed thinner than the first portion, and is continuous to the first portion adjacent to the second portion.
