Claim Text:
1. A display panel, comprising: a first substrate and a second substrate opposed to each other; a blue phase liquid crystal layer arranged between the first substrate and the second substrate; a first polarizer located on a side of the first substrate away from the blue phase liquid crystal layer; a second polarizer located on a side of the second substrate away from the blue phase liquid crystal layer; a first electrode located on a side of the first substrate facing the blue phase liquid crystal layer; a second electrode located on a side of the second substrate facing the blue phase liquid crystal layer, the first electrode and the second electrode being configured to generate a vertical electrical field; a first prism layer located between the blue phase liquid crystal layer and the first polarizer and configured to deflect an incident light and direct the deflected incident light towards the blue phase liquid crystal layer; and a second prism layer located between the blue phase liquid crystal layer and the second polarizer and configured to deflect the incident light having passed through the blue phase liquid crystal layer and direct the deflected incident light towards the outside of the display panel; wherein the first prism layer comprises a plurality of first triangular prisms and the second prism layer comprises a plurality of second triangular prisms and both the first triangular prisms and the second triangular prisms are isosceles triangular prisms; wherein the first triangular prisms each comprise a bottom face which is parallel to the first substrate and two refractive faces which are inclined at an angle of 30˜80 degrees with respect to the bottom face thereof; and/or the second triangular prisms each comprise a bottom face which is parallel to the second substrate and two refractive faces which are inclined at an angle of 30˜80 degrees with respect to the bottom face of the second triangular prism; and wherein the first triangular prisms have the same size as that of the second triangular prisms, and the first triangular prisms and the second triangular prisms are arranged such that their tops are opposed to each other.
