  • Liquid crystal display device and method of driving the same
    Patent number: 9082360
    Abstract: A liquid crystal display device includes an array substrate, a counter substrate and a liquid crystal layer held between the array substrate and the counter substrate. A display portion having a plurality of pixels arranged in a matrix is formed of the substrates and the liquid crystal layer. Each of the pixels includes a pixel electrode and a counter electrode arranged opposing to the pixel electrode. A driving portion is formed on the array substrate to supply a pixel voltage to the pixel electrode. A correcting circuit is formed on the array substrate to correct the voltage supplied to the pixel electrode by adding a predetermined DC voltage to the voltage supplied to the pixel electrode corresponding to gradations to be displayed in the pixel.

  • LIQUID CRYSTAL DISPLAY DEVICE
    Publication number: 20110242469
    Abstract: In one embodiment, a liquid crystal display device includes a first substrate, a second substrate and a liquid crystal layer held between the first and second substrates. The first substrate includes a first insulating substrate, and a pixel electrode and a counter electrode formed on the first insulating substrate. The second substrate includes a second insulating substrate. A first light shield layer is formed on a surface of the second insulating substrate apart from an end of the second insulating substrate opposing to the first substrate, and having a frame portion in a frame shape. Furthermore, a second light shield layer is arranged adjoining the first light shield layer extending up to the end of the second insulating substrate opposing to the first substrate. A third light shield layer to shield light is provided between the first light shield layer and second light shield layer.
