Backlight assembly and liquid crystal display apparatus having the same

A backlight assembly comprising:

• a lamp that generates light;
• and
• a light guiding plate including:
• a light incident surface into which the light generated from the lamp is incident;
• a light reflecting surface extended from a side of the light incident surface, the light reflecting surface including a prism pattern having a plurality of prisms adjacent to one another, wherein a height of each of the prisms between the light incident surface and a first point increases as a distance from the light incident surface to the first point increases, the first point being spaced a predetermined distance from the light incident surface, and wherein further each of the prisms includes a recess on a ridge thereof between the light incident surface and the first point;
• and
• a light exiting surface extended from another side of the light incident surface, the light exiting surface and the light incident surface forming an angle smaller than about 90 degrees, the light exiting surface and the light reflecting surface face each other.

A liquid crystal display apparatus comprising:

• a backlight assembly including:
• a lamp that generates light;
• and
• a light guiding plate including a light incident surface into which the light generated from the lamp is incident, a light reflecting surface extended from a side of the light incident surface, and a light exiting surface extended from another side of the light incident surface to form an angle of less than about 90 degrees with respect to the light incident surface, the light reflecting surface including a prism pattern having a plurality of prisms adjacent to one another, wherein a height of each of the prisms between the light incident surface and a selected position of a corresponding prism increases as a distance from the light incident surface to the selected position increases, the selected position being spaced a predetermined distance from the light incident surface, and wherein further each of the prisms includes a recess on a ridge of a corresponding prism between the light incident surface and the selected position, and the light exiting surface and the light reflecting surface face each other;
• and
• a liquid crystal display panel that displays an image using light received from the light guiding plate.
