Liquid crystal display device and display panel thereof

The invention relates to the technical field of display. The invention provides a liquid crystal display device and a display panel thereof. The display panel comprises an array substrate, a color film substrate, a liquid crystal layer located between the array substrate and the color film substrate and frame sealing glue surrounding the liquid crystal layer, wherein the array substrate and the color film substrate are arranged in a box-to-box mode. The display panel is provided with a display area and a non-display area; in the non-display area, the color film substrate is provided with a blocking unit protruding towards one side of the array substrate, and/or the array substrate is provided with a blocking unit protruding towards one side of the color film substrate. The blocking unit comprises a first blocking unit and a second blocking unit; the projection of the frame sealing glue in the first direction is not overlapped with the projection of the first blocking unit in the first direction, and the projection of the frame sealing glue in the first direction is overlapped with the projection of the second blocking unit in the first direction. The second blocking unit is located on the side, away from the display area, of the first blocking unit. The possibility of frame glue puncture can be reduced.
