Liquid crystal display apparatus
According to one embodiment, a liquid crystal display apparatus includes a display region including a plurality of display pixels arrayed in a matrix, an array substrate including a plurality of first electrodes which are arrayed in a matrix, second electrodes which are arranged on the same layer as a layer of the first electrodes and connect the first electrodes to each other, and third electrodes which are arrayed in a matrix on the first electrodes and the second electrodes, a countersubstrate which is arranged to face the array substrate, and a liquid crystal layer which is interposed between the array substrate and the countersubstrate.
1. A display device comprising:
a plurality of pixels;
switching elements having a first switching element and a second switching element, and arranged in the plurality of pixels;
signal lines electrically connected to the switching elements;
pixel electrodes having a first pixel electrode electrically connected to the first switching element in a first contact portion and a second pixel electrode electrically connected to the second switching element in a second contact portion;
