Abstract: A phase-transition optical isomer compound is described, a transparent EL display device including the phase-transition optical isomer compound and a method of fabricating the EL display device, where a phase of the phase-transition optical isomer compound is transited by light irradiation and a second electrode of the EL display device is selectively deposited without a masking process.

Abstract: A backplate of a display device has a first rigid region, a second rigid region spaced apart from the first rigid region, and a flexible region between the first rigid region and the second rigid region. The flexible region includes an electromagnet and encloses a magneto-rheological fluid that suspends magnetic particles. The rigidity of the flexible region changes responsive to changes in magnetic field generated by the electromagnet.
