A new kind of in-cell solution-processed broadband quarter wave plate for the circular polarizer made of liquid crystal polymer using coating technique has been proposed and manufactured in this work. The transmittance and reflectance spectrum can show high ambient contrast ratio (ACR) improvement for the light emitting display system.
