Plane light source and flexible plane light source
A plane light source including a circuit substrate, a plurality of sets of side-view light-emitting devices (LEDs), and a diffusive light-guiding layer is provided. The side-view LEDs are arranged in array over the circuit substrate and are electrically connected with the circuit substrate. The diffusive light-guiding layer covers the side-view LEDs, wherein the diffusive light-guiding layer includes a plurality of diffusive light-guiding units arranged in array and connected to each other. Each of the diffusive light-guiding units is respectively corresponded to illumination coverage of one set of side-view LEDs. Each set of side-view LEDs at least includes two side-view LEDs for emitting light respectively along two different directions and towards into one single diffusive light-guiding units.
