Transfer Fabrication of Liquid Crystal Devices with Microgroove and Wall Structure on Plastic Substrate for Flexible In-plane Switching Liquid Crystal Displays

In this paper, we propose the in-plane switching liquid crystal device with a microgroove and wall structure, fabricated by a transfer method for printable manufacturing of large-area flexible liquid crystal displays. We confirmed that the liquid crystal devices have a higher transmittance than conventional devices, and that a reduction of the thickness of the residual polymer film is necessary to decrease the driving voltage. Similar to the technique used on glass substrates, fabrication of flexible liquid crystal devices using a plastic substrate is possible using silicone elastomer.
