Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an LCD display capable of lowering the brightness image taken by an ultrasonic photographing apparatus often used in a dark environment down to a level suited for a dark place and displaying the image. SOLUTION: The apparatus comprises a liquid crystal matrix allowing the light transmittance to be controlled every pixel, LCDs for emitting back illuminated lights forwards through the matrix to display an image, a first memory means for storing first image data for displaying a predetermined image on the LCDs, and a second memory means for storing second image data for displaying the same image data at a lower brightness than the first image data. Either the first or second image data are selectively supplied to the LCDs.
