The present invention provides a backlight component capable of improving brightness and reducing manufacturing cost. The backlight component includes a light source producing lights, a light guide board, a reflective film configured on the lower part of the light guide board, and at least one optical film provided at the upper side of the light guide board. The light guide board includes an upper surface formed with mutually connected upper prismatic patterns, an incident face of the incident light from the light source, and a lower surface including mutually isolation formed lower prismaticpatterns and flatness sections formed between the lower prismatic patterns, wherein, the distance between the upper surface and the flatness section is segmentally when the distance between the flatness section and the incident face becomes larger, and the lower prismatic patterns include a first inclined plane formed by sloping towards the upper direction from the flatness section at the front end, and a second inclined plane which is formed by sloping towards the lower direction from the first inclined plane and is connected to the flatness section at rear end. |
