    • PURPOSE: A backlight unit and display device is provided to reduce the thickness and improve a picture quality of a display image. CONSTITUTION: A backlight unit includes as follows. A first layer. A plurality of light sources arranged on the first layer. A second layer is located on the first layer arranged on the plurality of light sources. A plurality of light sources includes as follows. A first light source(220) emits the light to a work direction. A second light source emits light to the same direction with the first light source and is arranged on a horizontal lien which is same with the first light source that is neighborly arranged with first light source. A third light source(222) emits light to the direction opposite to the first light source and is arranged on diagonal line with the first light source and is arranged between the first light source and the second light source. A first distance is the distance between a light emitting surface of the first light source and a light emitting surface of the second light source. A second distance is the distance between the center of a light emitting surface of the first light source and the center of a light emitting surface of the third light source. The first distance is smaller or the same as the second distance.
    • 目的:提供背光单元和显示装置,以减小厚度并提高显示图像的图像质量。 构成:背光单元包括如下。 第一层。 布置在第一层上的多个光源。 第二层位于布置在多个光源上的第一层上。 多个光源包括如下。 第一光源(220)将光发射到工作方向。 第二光源与第一光源发射相同的方向的光,并且被布置在与邻近配置有第一光源的第一光源相同的水平留置上。 第三光源(222)向与第一光源相反的方向发光,并且与第一光源对准地布置,并且布置在第一光源和第二光源之间。 第一距离是第一光源的发光表面和第二光源的发光表面之间的距离。 第二距离是第一光源的发光面的中心与第三光源的发光面的中心之间的距离。 第一距离较小或与第二距离相同。

    • PURPOSE: A backlight unit and a display device using the same are provided to improve a picture quality of a display image by providing light with uniformed brightness to a display panel. CONSTITUTION: A plurality of light sources emits light by being formed on a first layer(210). A second layer(230) is arranged on upper side of the first layer and covers the light sources. The second layer includes a plurality of bubbles(231). Resin comprising the second layer has larger refractive index than the bubble. A backlight unit(200) is a substrate in which a light source is mounted. The refractive index of a third layer is larger than the refractive index of the second layer. A third layer includes a plurality of scattering particles. Density of bubbles included in the third layer is higher than the density of bubbles included in the second layer.
    • 目的:提供背光单元和使用其的显示装置,以通过向显示面板提供具有均匀亮度的光来提高显示图像的图像质量。 构成:多个光源通过形成在第一层(210)上而发光。 第二层(230)布置在第一层的上侧并覆盖光源。 第二层包括多个气泡(231)。 包含第二层的树脂具有比气泡更大的折射率。 背光单元(200)是安装有光源的基板。 第三层的折射率大于第二层的折射率。 第三层包括多个散射颗粒。 包含在第三层中的气泡的密度高于包含在第二层中的气泡的密度。
