(a) and ip-SFR (b) modes and its corresponding LC molecular orientation and transmittance in a voltage-on state. The second row indicates transmittance in the cross-sectional line I–I′ . Both modes have the same electrode layers but different shape of common electrode. This figure was reproduced from Katayama

Here, LC directors located in vertical lines do not switch and the distance
l between these two lines exists, orthogonal to cell gap
d. (c,d) Top view of desired (c) and undesired (d) status of LC director distribution with applied voltage and its corresponding luminance photomicrographs of desired (e) and undesired (f) status with applied voltage. The alternate bright and dark stripes of luminance in the desired state change to irregular in the undesired state (circle). (g) Electrode structure of SL-IPS to control the rotating direction of LC directors with trunk and branch parts. (h) Details of equipotential lines and vector orientation lines with electrode structure. The black bars indicate LC directors. (i) In-plane luminance distribution in SLC-IPS test cell.

Here, the LC medium exists under two crossed polarizers. Two electrode layers on the bottom substrate exist with a passivation layer between them as in the FFS mode and a common electrode exists on the top substrate. The common electrode has open gap
g and the size of a pixel electrode can be adjustable depending on display resolutions. The arrows indicate the electric field direction between pixel and common electrodes. In the voltage-on state, LC directors experience bend deformation as indicated in Figure 24.1(b). This figure was reproduced from Yoon

μm (b) and 3
μm (c) in the UFS cell. (d) Calculated voltage-dependent transmittances at three different
g-values and (e) time-dependent transmittance curves in the FFS and UFS devices. In the FFS device, the electrode width and gap between patterned electrodes are 3 and 4.5
μm, respectively. The thickness of the passivation layer is 300 nm. The physical properties of LCs tested are as follows: dielectric anisotropy Δ

γ =
80 mPa s, splay/twist/bend elastic constants = 16.9/8.42/19.2 in pN and the
d is 4 m. The A and P in (d) represent the analyser and polarizer, respectively. This figure was reproduced from Yoon
