A multi‐domain vertical alignment device using a new method for forming protrusions is proposed. In the device, the photo‐sensitive ink was printed with line shape forming protrusions on the substrates. Then the cell was assembled with crossed‐line shaped protrusions on top and bottom substrates. Owing to symmetrically positioned protrusions, the vertically aligned LCs form multi‐domain in on state and with the help of surface polymer‐stabilization technique, the response time is greatly improved. Consequently, the proposed device using protrusion by any printing method shows excellent performance such as wide‐viewing‐angle and fast response time without conventional photolithography process.
