According to an embodiment of the present invention, an integrated light guide panel on which prism and optical patterns are formed and which can replace the role of optical films such as a prism sheet and a diffusion sheet which are installed in traditional backlight unit and indoor and outdoor lighting unit, is provided to reduce the high costs for using the optical films. For this, an embodiment of the present invention provides the integrated light guide panel which comprises: a light guide member which receives incident light from a certain light source, wherein four composite patterns divided on one side of the light guide member form a plurality of areas, and the composite patterns are formed to be orthogonal to the adjacent patterns; a prism pattern which concentrates the incident light and outputs the incident light on the front surface of the light guide member; and a diffusion pattern which are formed as a plurality of bumps between prism patterns which are composite patterns, distracts the incident light, and diffuses the incident light to the front surface of the light guide member. |
