The present invention provides a liquid crystal display panel and a liquid crystal display device each of which exhibits a sufficiently high response speed and an excellent transmittance. The liquid crystal display panel of the present invention includes a first substrate; a second substrate; and a liquid crystal layer disposed between the substrates, the first substrate and the second substrate each comprising an electrode, the electrode of the second substrate including a pair of comb-shaped electrodes and a planar electrode, the liquid crystal layer containing liquid crystal molecules which are inclined from an orthogonal direction to the main faces of the substrates between the pair of comb-shaped electrodes in a plan view of the main faces of the substrates when a voltage lower than a threshold voltage is applied.
