Abstract
A biochip includes a liquid crystal panel having liquid crystal cells each corresponding to each sample on a substrate. The liquid crystal panel includes an upper polarization filter, an upper transparent electrode, an upper orientation film, a liquid crystal, a lower orientation film, a lower transparent electrode and a lower polarization filter in this order. By application of voltage to a desired liquid crystal cell, external light is selectively radiated onto the sample. Thus, it is possible to achieve downsizing, cost reduction and high-speed operation of a biochip reader.
