Abstract: 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 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.

Abstract: The present invention provides a mirror display that has improved design aesthetics and makes it possible to sufficiently improve visibility in mirror mode in dark environments. The mirror display according to the present invention includes a half mirror plate having a half mirror layer, a display device, a case, and an auxiliary illumination unit that includes an auxiliary light source. The case supports at least the half mirror plate and the display device and includes an outer frame that covers an edge of a front surface of the half mirror plate when viewed in a plan view from a viewing side. The display device is arranged on a rear side of the half mirror plate. The auxiliary light source is arranged on the rear side of the half mirror plate, the display device, or the outer frame. The auxiliary illumination unit is controlled separately from the display device and emits light towards the viewing side when the mirror display is in mirror mode. As measured on the viewing side, a brightness of the light emitted from the auxiliary illumination unit is greater than a brightness of the display device when the display device is in a white display state.

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.
