Light emission device and display device using the same as light source

摘要

A light emission device (101) for simplifying a structure of an electron emission unit and a manufacturing process thereof is provided. A display device using the light emission device as a light source is also provided. The light emission device includes a vacuum panel having a first substrate (12) and a second substrate (14) facing each other. A sealing member (16) is between the first and second substrates. Recesss portions (28) each have a depth into a side of the first substrate facing the second substrate. Cathode electrodes (24) are in corresponding recesses. Electron emission regions (22) are on corresponding cathode electrodes. A gate electrode (26) is fixed at one side of the first substrate at a distance from the electron emission regions. A light emission unit (20) is at one side of the second substrate. The gate electrode includes a mesh unit (32) having openings for passing through an electron beam and a supporting member surrounding the mesh unit.
