Abstract: 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.

Abstract: A display panel and a display apparatus are provided in the present disclosure. The display panel includes a control chip in the non-display region on a first side, where the control chip is at least electrically connected to a data line; and along the second direction, the first side is adjacent to the display region; and includes a heating drive element in the non-display region on the first side, where the heating drive element is electrically connected to a heating wiring through a heating bus. The display panel further includes a gate drive element in the non-display region on a second side, where the gate drive element is electrically connected to a gate electrode line and electrically connected to the control chip through a first lead. Along a third direction, the heating bus is not overlapped with the first lead, where the third direction is perpendicular to the substrate.
