A suitable backlight light source mounted on a thin liquid crystal display device is provided. A light-emitting diode placed on a substrate, a first optical resin formed in a dome shape covering the light-emitting diode and having a height L1, and a diffusion material for diffusing light emitted by the light-emitting diode. And a second optical resin formed in a column shape on the first optical resin using the mixed optical resin and having a height L2 (> L1). [Selection] Figure 5 |
