[0026] Such as figure 1 As shown, a liquid crystal display device which is an example of the display device according to the first embodiment includes a substantially rectangular flat liquid crystal display panel 1 . The liquid crystal display panel 1 includes a pair of substrates (ie, an array substrate 3 and a rear substrate 4 ) and a liquid crystal layer 5 as a light modulation layer disposed between the pair of substrates. The liquid crystal display panel 1 includes a rectangular effective display portion 6 for displaying images. The effective display portion 6 is composed of a plurality of display pixels PX arranged in a matrix.

[0027] The array substrate 3 includes a plurality of scanning lines Y (1, 2, 3, . A plurality of signal lines X (1, ​​2, 3, . Pixel electrode 8.

[0028]The switching element 7 is made of, for example, a thin film transistor (TFT). The switching element 7 has a gate electrode 7G electrically connected to (or integrally formed with) the relev...
