FABRICATION METHOD FOR FIELD EMISSION ARRAY TYPE LIGHT EMITTING UNIT

摘要

A method of manufacturing a field emission array type light emitting unit is provided to improve optical efficiency as improving uniformity of emitted light. A field emission array type light emitting unit includes a rear substrate(20), a front substrate(10), and plural spacers(33). The rear substrate includes a cathode electrode and a CNT(Carbon Nano Tube) emitter. The front substrate includes an anode electrode and a fluorescent layer(12). The spacers are arranged to maintain a constant distance between the front and rear substrates. Diffusion patterns(11) are formed on a front surface of a glass substrate for the front substrate through a wet etching process. The front surface of the glass substrate is divided into at least two regions. The diffusion patterns having different diffusion ratios are formed on the respective regions on the glass substrate.
