Abstract
We propose a reflective three-dimensional (3D) display using a cholesteric liquid crystal (ChLC) with an inner patterned retarder producing half-wave retardation. The inner patterned retarder, fabricated by selective ultra-violet exposure to the aligned reactive mesogen, divides the circularly polarized light reflected from the ChLC layer into two orthogonal circular polarizations. These reflected orthogonal polarizations construct stereoscopic 3D images without any optical components such as a polarizer and backlight unit.
Highlights
Flat panel displays have been developed to achieve excellent performances such as low power consumption, high contrast ratio, high definition, and light weight

Summary
Flat panel displays have been developed to achieve excellent performances such as low power consumption, high contrast ratio, high definition, and light weight. In the glasses-based 3D displays, to produce the binocular disparity, a liquid crystal display (LCD) panel generates two different images arriving at the left and right eyes. Various stereoscopic 3D displays with good display performances have been developed and fabricated, a reflective 3D display with low power consumption has not been proposed so far. Since the ChLC display using the polarization-selective reflection is operated in a reflective mode without a polarizer, the patterned retarder can be embedded within the LCD panel. We could obtain stereoscopic 3D images through dividing the reflected light into two orthogonal polarizations This reflective 3D display does not require a color filter and backlight unit since the reflective ChLC mode is used [10,11,12]. The reflective 3D display proposed here is expected to create novel 3D displays with low power consumption due to their memory characteristics in the conventional ChLC modes and the reflective configuration without backlight unit
