    • The backlight assembly includes a light source and a light guide plate. The light source includes a plurality of light generating parts that generate a first light. The light guide plate includes side surfaces, a light exiting surface and a light reflecting surface. The light exiting surface has a plurality of luminance-compensating patterns. The light reflecting surface faces the light exiting surface. The first light enters into the light guide plate via the light incident surface to form a second light. The second light is reflected on the light reflecting surface toward the light exiting surface to form a third light. The third light exits from the light guide plate via the light exiting surface. The luminance-compensating patterns uniformize a luminance of the third light. A thickness of the light guide plate decreases in a direction from the light incident surface to a center of the light guide plate
    • 背光组件(100)包括光源和导光板(40)。 光源包括产生第一光的多个发光部(10,20)。 导光板(40)包括侧表面(41,43),光出射表面(47)和光反射表面(45)。 光出射表面(47)具有多个亮度补偿图案(47a)。 光反射面(45)面向光出射面(47)。 第一光经由光入射面(41,43)进入导光板(40),形成第二光。 第二光在光反射面(45)上朝向光出射面(47)反射,形成第三光。 第三光经由光出射面(47)从导光板(40)射出。 亮度补偿图案(47a)使第三光的亮度均匀化。 导光板(40)的厚度在从光入射面(41,43)到导光板(40)的中心的方向上减小。
