CIRCUIT BOARD AND DISPLAY DEVICE

摘要

The purpose of the present invention is to provide a circuit board and a display device wherein a patterned film is disposed in a manner that can sufficiently reduce the increase in capacitance and sufficiently minimize the degradation of display quality due to signal delay, while sufficiently shielding the lost part of a light shielding member with the patterned film. The present invention provides a circuit board used for a display device in which pixels are used to make an image. The circuit board comprises: a plurality of first wires and a plurality of second wires intersecting with the first wires; a thin-film transistor element; a plurality of pixel electrodes electrically connected to the drain electrodes of the thin-film transistor element; and a patterned film. In a planar view of the principal surface of the circuit board, two of the plurality of first wires extend parallel to each other between pixels, and the patterned film has a linear portion extending along the first wires between the mutually extending two first wires.
