Abstract
An LED device includes at least two lead electrodes disposed opposite to each other, a transparent molding, a light-emitting element, a resin layer, and a light-blocking layer. The transparent molding is positioned between the lead electrodes and around edges of the lead electrodes to form a recess, the light-emitting element disposed in the recess. The resin layer is formed in the recess of the transparent molding and covering the light-emitting element. The light-blocking layer is disposed on the resin layer, with its upper surface coplanar with an upper surface of the transparent molding. An LED backlight module includes a diffusion plate, a brightening film, a microlens-prism film, a quantum dot film, a plurality of LED devices in a substrate, and a driving circuit. The plurality of LED devices forms a plurality of groups arranged in an N*N array, such that LED devices of adjacent rows are misaligned with each other.
