Abstract
An inspection is performed using a captured image obtained by irradiating, with blue light, an optical wavelength conversion sheet that includes a quantum dot layer which contains a quantum dot emitting red light and green light by receiving blue light with blue light from a back surface side and imaging from a front surface side with a camera. A filter which cuts the blue light and transmits the red light and the green light is disposed between the camera and the optical wavelength conversion sheet.
