“…However, LC alignment is still based on the rubbing of polyimide (PI). The traditional rubbing process for LC alignment has major limitations such as debris and electrostatic discharge, which produce local defects and streaks and result in the degradation of the display resolution [1][2][3][4][5][6]. Over the past several years, there have been a number of challenges to replace PI based rubbing process by nonrubbing methods from methods from traditional oblique deposition, the UV exposure to up-to-data u rubbing, the nanoimprint lithography, and the nanostructured alignment method, which provides controllabililty, nonstop process, and high resolution display, has been intensively investigated with inorganic materials so far.…”
