An optical lens, an optical module, a backlight assembly and a display apparatus having the same with which it is disclosed it. The display apparatus includes an optical module, a storage container, a light mixing member, the diffusion plate and the display panel. An optical module substrate, and disposed on the substrate, the point light source and the first lens unit with a housing to accommodate each point light source, the surrounding parts of the first lens 2 for generating a color light by the applied power over a substrate It includes a first optical lens including a connecting portion connecting the first lens in the lens unit and second lens unit. Storage container and housing the optical module, a light mixing member is a white light generated by mixing the color light emitted from the optical module. The diffuser plate is placed in a storage container, it diffuses the white light to generate a diffusion light. The display panel is placed in a storage container, and generates an image based on the diffused light.
