Blue phase liquid crystal panel and blue phase liquid crystal display device

A blue phase liquid crystal display device, comprising a blue phase liquid crystal panel, which comprises:

• an upper substrate and a lower substrate that are arranged facing each other, and blue phase liquid crystal that is arranged between the upper substrate and the lower substrate,
• wherein the upper substrate, on a surface thereof facing the blue phase liquid crystal, is provided with a first electrode base layer which has a plurality of first protrusions, and the lower substrate, on a surface thereof facing the blue phase liquid crystal, is provided with a second electrode base layer which has a plurality of second protrusions;
• wherein the first protrusions each extend to a position between two adjacent second protrusions, and the second protrusions each extend to a position between two adjacent first protrusions;
• wherein the first protrusions are provided with a common electrode, and the second protrusions are provided with a pixel electrode;
• wherein the pixel electrode comprises a first pixel electrode and a second pixel electrode;
• wherein one of the two adjacent second protrusions is provided with the first pixel electrode, and the other one of the two adjacent second protrusions is provided with the second pixel electrode;
• wherein a horizontal electric field is formed between the first pixel electrode and the second pixel electrode;
• and
• wherein a second common electrode is arranged between the pixel electrode and the lower substrate in an insulation manner, and a top surface area of the first protrusion facing the second common electrode is not provided with a common electrode.
