Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p>We demonstrate a liquid crystal (LC) mode switched by combined fringe and in‐plane switching (IPS) fields, which are self‐adjusted by adopting a bottom floating electrode for enhanced electro‐optical properties. In our LC mode structure, conventional IPS electrodes are formed as pixel electrodes and common electrodes on an insulating layer, and floating electrodes that are patterned per the sub‐pixels are formed under the insulating layer. When the areas of the pixel and common electrodes are same, the voltage of the bottom floating electrode is spontaneously determined to be half the value of the pixel voltage, which ideally generates symmetric fringe fields with both pixel and common electrodes. Due to the in‐plane fields additionally generated between the pixel and common electrodes, the proposed LC structure shows higher transmittance than fringe‐field switching (FFS) and IPS LC modes. Transmittance of the conventional FFS and IPS LC modes is highly sensitive to the in‐plane electrode's width and spacing condition, but the proposed LC mode shows good transmittance without degradation under large variation condition of the in‐plane electrode's spacing‐to‐width ratio.</p> </abstract>
