The structure and the photographs of the LE-LCD with photopatterned alignment in the electric field-off and field-on states using light-emitting LC mixture. The LC mixture = nematic LC PA0182 + 0.1 wt% TPE-PPE. a, b The LE-LCD in the electric field-off condition. There are two regions in the device that are aligned orthogonally. Under UV irradiation, the regions with and without figures in the device will be alternately bright and dark, viewing through the rotatable polarizer. c The LE-LCD in the electric field-on condition. Under UV irradiation, both two regions will be light-emitting and the figures disappeared. Reprinted with permission from ref. [107] Copyright 2014 Wiley-VCH
