Abstract:
A liquid crystal apparatus includes a substrate, a pixel electrode, common wiring, a TFT provided between the substrate and the common wiring, a scanning line provided between the substrate and the TFT along a first direction, a capacitance element provided between the substrate and the scanning line and overlapping the scanning line in plan view, and a second relay electrode electrically coupled to the common wiring and overlapping the scanning line in plan view. The second relay electrode and a first capacitance electrode serving as one electrode of the capacitance element are electrically coupled to each other through a contact hole overlapping the scanning line and the first capacitance electrode in plan view. The scanning line has a cutout portion provided between the second relay electrode and the first capacitance electrode and surrounding at least three directions of the circumference of the contact hole.
