Abstract: A technique is provided that reduces dullness of a potential provided to a line such as gate line on an active-matrix substrate to enable driving the line at high speed and, at the same time, reduces the size of the picture frame region. On an active-matrix substrate (20a) are provided gate lines (13G) and source lines. On the active-matrix substrate (20a) are further provided: gate drivers (11) each including a plurality of switching elements, at least one of which is located in a pixel region, for supplying a scan signal to a gate line (13G); and lines (15L1) each for supplying a control signal to the associated gate driver (11). A control signal is supplied by a display control circuit (4) located outside the display region to the gate drivers (11) via the lines (15L1). In response to a control signal supplied, each gate driver (11) drives the gate line (13G) to which it is connected.

The color filter board includes a light blocking section formed in a grid and color sections that are formed in areas surrounded by a pattern of the light blocking section in different colors from area to area. The color sections form display pixels on a combination basis. The display panel includes a light blocking area in at least a section of an edge along an outline of the display panel. The method includes setting the color sections that do not form the display pixels among the color sections adjacent to the light blocking area in a plan view of the display panel constantly in the black state.

Abstract: The present invention addresses the problem of reducing power consumption when switching a gate line between a selected state and a non-selected state, and of providing a narrower frame for an active matrix substrate. A gate driver (11) that scans each gate line is formed inside a display area in an active matrix substrate (20a) having gate lines (13G) and data lines formed therein. The gate driver (11) switches the gate line to either a selected state or a non-selected state, in accordance with a control signal supplied via a line (15L). The gate driver (11) includes a high-charge drive circuit (11a), a low-charge drive circuit (11b), and a shift register (11c). The high-charge drive circuit is supplied with a first DC voltage signal corresponding to the selected state via the line (15L), and charges the gate line to the potential of the first DC voltage signal. The low-charge drive circuit (11b) is supplied with a second DC voltage signal corresponding to the non-selected state, and charges the gate line to the potential of the second DC voltage signal.
