Line light source device, plane light emission device, plane light source device, and liquid crystal display

摘要

In the line light source device and the plane light emission device, first recesses 14 are formed between adjoining light emission elements 5, on surfaces of sealing resin layers 10 opposite to the board 4. The line light source device and the plane light emission device, in which the light emission elements are coated with resin, have a simple configuration and high uniformity in luminous intensity in an emission end face of the device.
