Disclosed is a blue phase liquid crystal display panel which includes an upper substrate and a lower substrate which are disposed opposite to each other, and blue phase liquid crystals provided between the upper substrate and the lower substrate. The upper substrate is provided with a first common electrode on a side facing the blue phase liquid crystals, and the lower substrate is provided with a second common electrode and a plurality of pixel electrodes on a side facing the blue phase liquid crystals. The pixel electrodes each extend towards the first common electrode, thus forming a horizontal electric field between the upper substrate and the lower substrate. According to the present disclosure, higher horizontal field intensity can be achieved so that the external drive voltage of the blue phase liquid crystals can be greatly decreased.

The present application claims the priority of Chinese patent application CN201510380874.9, entitled “Blue phase liquid crystal display panel” and filed on Jun. 30, 2015, the entirety of which is incorporated herein by reference.
The present disclosure relates to the technical field of liquid crystal displays, and in particular, to a blue phase liquid crystal display panel.
In the technical field of liquid crystal displays, blue phase liquid crystals have been widely used in liquid crystal display devices in virtue of their excellent properties. For instance, due to the optical isotropy of blue phase liquid crystals, the liquid crystal display devices using blue phase liquid crystals have advantages such as high response rate, wide viewing angle, excellent dark state, etc. Meanwhile, being different from other liquid crystal display devices, liquid crystal display devices using blue phase liquid crystals do not need an alignment layer, which simplifies the manufacturing process of liquid crystal display devices, and further reduces the manufacturing cost. In addition, when the thickness of the liquid crystal cell of the display device using blue phase crystals is larger than the penetration depth of the electric field, the effects of the change of thickness of the liquid crystal cell on transmissivity can be neglected. This feature enables blue phase liquid crystals particularly suitable for the manufacture of large screens or single board liquid crystal display devices.
For further illustrating the technical solutions provided in the embodiments of the present disclosure, a brief introduction will be given below to the accompanying drawings involved in the embodiments.
