Flexible display devices are widely and extensively studied for using the applications such as smart cards, PDA, head
mounted displays and all kinds of mobile display because of their lighter weight, thinner packaging, and flexibility.
However, it has some obstacles such as mechanical stability and tight adhesion of two plastic substrates. In this
presentation, we will suggest a new bonding technologies with rigid spacers and bonding materials, which will serve
mechanical stability and good adhesion strength. The micro-contact printing method is used to place bonding material
on the rigid spacers that may be easily applicable to roll-to-roll fabrication processes. The performances of prototype
samples fabricated will also be demonstrated by this technology.
Anisotropic phase-separation of liquid crystal and polymer composite is highly applicable for obtaining the durable
electro-optic devices. In this presentation, the theoretical model for phase separation phenomena based on the onedimensional
kinetic approach is introduced. For the applications of phase-separated LCs, we propose the fabrication of
mechanically stable flexible display and electrically controllable microlens array using two- or three-dimensional
anisotropic phase separation. Since LC molecules are isolated by polymer structure due to the anisotropic phase
separations, resultant devices show very good mechanical stability against external pressure and stable electro-optic
