Abstract:
Provided is a display panel that reduces occurrence of display irregularities in a display region even in a case where driving circuits that switch gate lines between selected and non-selected states are provided in the display region. A display panel of the present invention includes an active matrix substrate and a counter substrate, the active matrix substrate being provided with a plurality of gate lines and a plurality of source lines. The active matrix substrate includes, in a display region, a driving circuit provided with respect to each of the gate lines, for switching the gate line between a selected state and a non-selected state. The display panel further includes, in a non-installation region where the driving circuit is not provided, an aperture ratio adjustment member that changes an aperture ratio in the non-installation region stepwise, in order to decrease a difference between a luminance in an installation region where the driving circuit is provided and a luminance in the non-installation region.
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.

In a liquid crystal display device, liquid crystal molecules are oriented in a vertical direction to the first substrate and the second substrate by the first molecule orientation film and the second molecule orientation film, respectively, in a non-driving state. A structural pattern is formed so as to extend in a first direction parallel to a surface of the liquid crystal layer and so as to form, in a driving state, an electric field periodically changing in a second direction that is parallel to the liquid crystal layer and vertical to the first direction. The liquid crystal molecules substantially tilt in the first direction in the driving state.
