Disclosed are a liquid crystal display panel and a liquid crystal display device for improving display brightness uniformity. The liquid crystal display panel includes a display substrate, a source driving circuit and a plurality groups of gate driving circuits. Each gate driving circuit includes a gate driving chip and a group of fan-out circuits, and resistances of wirings of different groups of fan-out circuits gradually increase along a direction away from the source driving circuit. The liquid crystal panel can improve brightness uniformity in different positions while displaying.
