A light source has a rear glass substrate and a front glass substrate having a plate surface disposed in facing relation to a principal surface of the rear glass substrate. The plate surface of the front glass substrate is coated with a phosphor. A two-dimensional array of electron emitters is disposed on the principal surface of the rear glass substrate. A space defined between the rear glass substrate and the front glass substrate is filled with a gas. The gas may be an Hg (mercury) gas or an Xe (xenon) gas.

A crosspiece precursor and a picture element assembly precursor are hardened at mutually different timings to form a crosspiece and a picture element assembly. For example, the crosspiece precursor is firstly hardened to form the crosspiece. After that, the picture element assembly precursor is hardened while allowing an upper end surface of the picture element assembly precursor to make pressed contact with an optical waveguide plate, by displacing an actuator element toward an actuator substrate. The picture element assembly, which is formed by hardening the picture element assembly precursor, reliably abuts against the optical waveguide plate when a display device is in a light emission state.
