VISIBLE-LIGHT BLOCKING MEMBER, INFRARED SENSOR INCLUDING THE VISIBLE-LIGHT BLOCKING MEMBER, AND LIQUID CRYSTAL DISPLAY DEVICE INCLUDING THE INFRARED SENSOR

摘要

In a visible-light blocking member, an infrared sensor including the visible-light blocking member, and a liquid crystal display including the infrared sensor, a visible-light blocking member is a structure including amorphous germanium or a compound of amorphous germanium and has higher transmittance for a wavelength of an infrared ray region than for a wavelength of a visible light region. Accordingly, sensitivity to infrared rays may be increased by applying the visible-light blocking member to the infrared sensor.
