A shading plate according to the present invention includes: an LCD panel disposed inside a vehicle, the LCD panel being vertically disposed at a position corresponding to a field of view of a driver, the light transmittance of the LCD panel being changed; a control unit including a body coupled to the LCD panel (10) so as to surround an upper end edge of the LCD panel (10), an illuminance sensor provided on a circumferential surface of a front side of the body to measure an amount of light entering the vehicle, and a control module for automatically controlling the transmittance of the LCD panel according to the illuminance value detected through the illuminance sensor; and a fixing unit coupled to the LCD panel and detachably coupled to a sun visor provided on a driver′s seat of the vehicle. The illuminance sensor detects the illuminance of the direct sunlight entering the vehicle or the reflected light reflected from the vehicle or a building and then automatically adjusts the transmittance of the LCD panel according to the detected illuminance value to protect the field of view of the driver.

    본 발명은 차량 내부에 설치되되 운전자의 시야와 대응되는 위치에 수직으로 배치되며 빛의 투과도가 변화되는 LCD패널과; 상기 LCD패널(10)의 상단 모서리를 감싸는 형태로 결합되는 본체와, 상기 본체의 전방측 외주면에 구비되며 차량 내부로 들어오는 빛의 양을 측정하는 조도센서 및 상기 조도센서를 통해 검출된 조도값에 따라 상기 LCD패널의 투과도를 자동으로 조절하는 제어모듈을 포함하는 제어부; 및 상기 LCD패널과 결합되며, 차량 운전석에 구비되는 선바이저에 착탈식으로 결합되는 고정수단;을 포함하여 이루어지며, 상기 조도센서가 차량 내부로 인입되는 햇빛의 직사광선이나 차량 또는 건물 등지에서 반사된 반사광의 조도를 검출한 다음 검출된 조도값에 따라 상기 LCD패널의 투과도를 자동으로 조절하여 운전자의 시야를 보호할 수 있도록 한 것을 특징으로 하는 투과도의 자동 조절을 통해 운전자의 시야를 보호할 수 있는 차량용 차광판을 개시한다.
