Abstract
A light-emitting device includes a panel substrate, a light-emitting chip, and a light extracting layer. The light-emitting chip is disposed on the panel substrate. The light extracting layer covers the light-emitting chip and the panel substrate, and the light extracting layer has a side portion. Taking the position where the edge of the light-emitting chip is in contact with the panel substrate as the origin, the side portion and the origin define a circle tangential to the surface of the side portion. The circle has a radius c which satisfies the following formula (1):
