摘要： An optical lens refracts and reflects a light to increase a luminance in a top direction of the optical lens and to decrease a luminance in a horizontal direction of the optical lens. The optical lens includes a central portion and a peripheral portion. The central portion has a convex shape. The peripheral portion has a concave shape. The peripheral portion surrounds the central portion. Therefore, a power consumption and a manufacturing cost are decreased.

摘要： A backlight assembly that improves color uniformity is presented. The backlight assembly includes a plurality of point light sources, an optical member on the point light sources, and a reflecting plate that is positioned to receive light that is reflected by the optical member. The point light sources includes a red light emitting diode generating red light, a green light emitting diode generating green light, and a blue light emitting diode generating blue light. The optical member transmits white light formed by mixing at least some of the red, green and blue lights and reflects the untransmitted portion of the red, green and blue lights. The reflecting plate, which receives the reflected light from the optical member, includes a plurality of patterns that reflect the incident red, green and blue lights, essentially “recycling” the light that did not get transmitted in the first pass.
