In a matrix device having two or more systems of electrode groups such as X and Y systems, the one or more electrode groups are grouped into groups each consisting of a plurality of pixel electrodes, connection wires are branched off and connected to the pixel electrodes so that the same signal is not supplied to the pixel electrodes of the same group but the same signal is supplied to one pixel electrode of two or more groups, switching elements are provided corresponding to the individual pixel electrodes, and a gate electrode and a gate insulating film of the switching elements are used in common in the same group. Accordingly, in the matrix device and manufacturing of the matrix device, the number of connection wires and driver ICs is reduced.
