Abstract
Provided are a polymer-dispersed liquid crystal (PDLC) display device and a method of manufacturing the same. The PDLC display device may include a PDLC layer between facing substrates, wherein the PDLC layer has at least two regions including polymers having different concentrations.
Claims18
A polymer-dispersed liquid crystal (PDLC) display device comprising:
- a first substrate and a second substrate configured to face each other;
- a first electrode and a second electrode on the first substrate and the second substrate, respectively;
- and
- a PDLC layer between the first electrode and the second electrode, the PDLC layer including at least one first region containing polymers in a concentration of about 5-25 wt % and at least one second region containing the polymers in a concentration higher than the concentration of the at least one first region,
- wherein each of the at least one first region and the at least one second region extend from an upper surface of the first electrode to a lower surface of the second electrode.

A method of manufacturing a polymer-dispersed liquid crystal (PDLC) display device, the method comprising:
- injecting a mixture including a photocurable material between a first electrode and a second electrode configured to face each other;
- applying light to the mixture through a photomask including patterns having different light transmittances;
- and
- forming a PDLC layer including polymers by absorbing the light into the photocurable material, the PDLC layer including at least one first region containing polymers in a concentration of about 5-25 wt % and at least one second region containing the polymers in a concentration higher than the concentration of the at one first region,
- wherein the at least one first and second regions are provided alternately and repetitively, and
- wherein each of the at least one first region and the at least one second region extend from an upper surface of the first electrode to a lower surface of the second electrode.
