Abstract: A light control panel including an image display region including a region corresponding to an image display region in a display panel and a region corresponding to a peripheral circuit region in the display panel is provided between the display panel and a backlight. A pattern image for controlling radiation of light emitted from the backlight to the display panel is displayed in the image display region in the light control panel according to an action state of the peripheral circuit in the display panel.

Abstract: An active matrix substrate includes a first pixel region defined by first and second source bus lines adjacent to each other and first and second gate bus lines adjacent to each other and further includes a first pixel electrode and a first oxide semiconductor TFT that are associated with the first pixel region. The first oxide semiconductor TFT includes an oxide semiconductor layer and a gate electrode electrically connected to the first gate bus line. The oxide semiconductor layer includes a channel region and a low-resistance region including first and second regions located on opposite sides of the channel region. When viewed in a direction normal to the substrate, the low-resistance region extends across the first source bus line to another pixel region and partially overlaps a pixel electrode disposed in the other pixel region with an insulating layer interposed therebetween.
