Abstract

A light-emitting device includes a light-emitting chip; a first light-transmitting layer formed on the light-emitting chip and has two side surfaces; and a first reflective layer formed on the light transmitting layer and extends beyond the two side surfaces of the light-transmitting layer.

Description

technical field [0001] The present invention relates to a light emitting device, in particular to a light emitting device comprising a reflective layer formed on a wavelength conversion layer. Background technique [0002] A light-emitting diode (Light-Emitting Diode, LED) has the characteristics of low power consumption, long service life, small size, fast response, and stable light-emitting and photoelectric characteristics. Recently, light emitting diodes are increasingly used in backlight units of liquid crystal displays. [0003] In a conventional direct type backlight unit, a lens is usually used to convert light from a light emitting device having a lambertian pattern into a Batwing light emitting pattern. The lens has a certain thickness, which is unfavorable for application in thin display devices. Contents of the invention [0004] An embodiment of the present invention discloses a light-emitting device, which includes a light-emitting chip, a contact pad, a fi...
