    摘要： An orientation film evaluating apparatus and a rubbing processing apparatus by which the orientation capability for a liquid crystal orientation film can be measured quantitatively with high sensitivity and accuracy even during an actual production process, and an orientation condition is controlled precisely so as to obtain a stable production condition and to improve productivity and yield therefor. The orientation film evaluating apparatus includes: a unit for radiating infrared light; a polarizing portion which polarizes the infrared at varied angles to an orientation film, and for irradiating the polarized infrared lights to the orientation film; a detection portion which detects infrared light reflected upon the orientation film; and an evaluating portion which obtains a difference of absorbance of infrared light detected by the detection portion with respect to a polarized direction of the orientation film, and which evaluates an orientation capability of the orientation film.
