Abstract

A liquid crystal display panel implementing a bistable liquid crystal and fabricating the same is disclosed in the present invention. Specifically, a method of fabricating a liquid crystal display panel having first and second substrates, the method includes forming a first electrode on the first substrate, forming a second electrode on the second substrate, assembling the first and second substrates, forming a bistable twist nematic liquid crystal layer between the first and second substrates, wherein the bistable twist nematic liquid crystal layer having a monomer, aligning the bistable twist nematic liquid crystal layer by applying electric fields, and forming polymer networks by exposing the bistable twist nematic liquid crystal layer to light.

Claims (8)

1. A liquid crystal display panel, comprising:

first and second substrates; and

a liquid crystal layer between the first and second substrates, wherein the liquid crystal layer has a photopolymerized monomer aligned perpendicular to the first and second substrates,

wherein the liquid crystal layer includes a bistable nematic liquid crystal layer.

2. The liquid crystal display panel of claim 1 , further comprising first and second electrodes on the first and second substrates, respectively.

3. The liquid crystal display panel of claim 2 , wherein the first and second electrodes are selected from a group consisting of indium tin oxide (ITO) and indium zinc oxide (IZO).

4. The liquid crystal display panel of claim 1 , wherein the liquid crystal layer contains a chiral dopant.

5. The liquid crystal display panel of claim 1 , wherein the liquid crystal layer contains at least one polymer network.
