Abstract
We proposed a half-wall structure in the in-plane switching (IPS) configuration of the nanoencapsulated liquid crystal (LC) display for reducing a driving voltage. The IPS electrodes were fabricated on top of the half-walls to enhance electric field strength through the whole LC layer. In addition, we demonstrated a self-masking process for the half-wall structure and the IPS electrodes without any additional mask-aligning process.
Highlights
Liquid crystal displays (LCDs) have been extensively studied and used for a wide range of display applications including mobile phones, monitors, and televisions because of their high image qualities with low power consumption

Summary
Liquid crystal displays (LCDs) have been extensively studied and used for a wide range of display applications including mobile phones, monitors, and televisions because of their high image qualities with low power consumption. LCDs have some intrinsic problems such as slow response time and narrow viewing angle characteristics. To overcome the viewing angle problem, multi-domain LC modes have been proposed such as in-plane switching (IPS) [1,2], fringe-field switching [3,4], optically-compensated bend [5,6], mutidomain vertical alignment [7,8,9], patterned vertical alignment [10,11], and axially symmetric aligned microcell [12], polymer-stabilized blue phase LC modes [13,14,15]. Because the nanoencapsulated LC layer has optically isotropic properties, excellent electro-optical characteristics including the contrast ratio and viewing angle were realized. The nanoencapsulated LCD exhibited fast response time characteristics because the LCs were surrounded by the polymer shell with a strong anchoring energy. The high operating voltage was a burden on real display application
