Patent attributes
An input device or an input/output device with higher sensing accuracy is provided. An input device or an input/output device with higher detection sensitivity is provided. A display device or an input/output device with high visibility is provided. A plurality of conductive layers arranged in a matrix has an outline including a linear portion parallel to a direction along an outline of a display region of a display portion and linear portions of adjacent two conductive layers face each other. Furthermore, in the plurality of conductive layers arranged in a matrix, a plurality of conductive layers arranged in a line in an oblique direction to the outline of the display portion are electrically connected to each other. Alternatively, a plurality of conductive layers arranged in a zigzag line along the outline of the display portion are electrically connected to each other.
