A liquid crystal display panel includes a first substrate, a second substrate, a liquid crystal layer arranged between the first and second substrates, and a secondary spacer. The secondary spacer has a bottom face fixed to the first substrate and a top face forming a gap with respect to the second substrate. The top face of the secondary spacer is provided with a first electrode and the second substrate is provided, at a location corresponding to the top face of the secondary spacer, with a second electrode. When the liquid crystal panel is driven and depressed, the first electrode electrically engages the second electrode so that a pixel electrode of the liquid crystal display panel at the depressed site is electrically connected to the ground thereby eliminating a high voltage difference between the pixel electrode and a common electrode.
