Abstract: Disclosed is a color and luminance measuring device including a filter unit including a case which covers the entire device and has a light incident part formed on one side thereof through which measured light emitted from an object to be measured is incident, a measurement unit which measures luminance and a color by receiving the measured light in the case, and a filter unit which is disposed on a movement path of the measured light in the case to selectively control the luminance of the measured light transmitted to the measurement unit and transmit the measured light, wherein the filter unit reduces the luminance of the measured light to a predetermined level when the measured light has luminance of a predetermined level or higher and transmits the measured light to the measurement unit.
