摘要： A liquid crystal display panel and a liquid crystal display device are provided. The liquid crystal display panel includes: a first substrate, a second substrate arranged opposite to the first substrate, and a liquid crystal layer sandwiched between the first substrate and the second substrate, in which a heating electrode is arranged on a side of the first substrate facing towards the liquid crystal layer. Heat generated by the heating electrode can directly act on liquid crystal molecules in the liquid crystal layer, so that the liquid crystal display panel can be quickly started and a response of the liquid crystal molecules in the liquid crystal layer can be accelerated in a low temperature environment, thereby guaranteeing the display quality of the liquid crystal display device in the low temperature environment.

摘要： Subject
The subject is to provide a liquid crystal display device having characteristics such as a short response time, a large voltage holding ratio, a low threshold voltage, a large contrast ratio, a long service life and a small flicker rate.
Means for solution
The means concerns the use of a liquid crystal composition for a liquid crystal display device including a first substrate, a second substrate and a liquid crystal composition having positive dielectric anisotropy, which is placed between these substrates, wherein the liquid crystal composition has a nematic phase and includes at least one compound selected from the group of compounds represented by formula (1) as a first component:

in formula (1), R 1 is alkyl or the like; ring A is 1,4-phenylene or the like; Z 1 is a single bond or the like; X 1 and X 2 is hydrogen or fluorine; Y 1 is fluorine or the like; and m is 0, 1, 2, 3 or 4.

摘要： 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.
