A liquid crystal display panel, a display device and an electric apparatus are disclosed. The liquid crystal display panel including a color filter substrate and an array substrate; pixel electrodes, common electrodes and an insulator layer that separates the pixel electrodes and the common electrodes are provided on the array substrate; a plurality of first protruding structures in an upward protruding direction and a plurality of second protruding structures in a downward protruding direction are provided inside the insulator layer; the first protruding structures and the second protruding structures are disposed alternately, the pixel electrode and the common electrode are respectively formed on the first protruding structures and the second protruding structures. The pixel electrodes and the common electrodes are formed on the protruding structures that are disposed alternately, so that the transmittance of the liquid crystal display panel is increased, and picture display quality of the liquid crystal display panel is improved.
