Zusammenfassung:	Provided is an optical plate that resolves white screen generation while maintaining emission brightness, a backlight assembly (2000) and a display device including the same. The optical plate is a light guide plate (100) for a liquid crystal display (700). The light guide plate (100) includes at least one plane in which a plurality of uneven patterns forming crests and valleys are formed in an uneven portion (120). The plurality of uneven patterns is formed such that the crests rise to a plurality of different heights.
