An EL device is constructed of an insulating substrate, and a first electrode, a first insulating layer, a luminescent layer, a second insulating layer and a second electrode, which are laminated on the insulating substrate in this order. The insulating layer is made by a method other than ALE, for example, sputtering or vapor deposition. The second insulating layer includes alternating layers of Al2O3 and TiO2, which are formed by ALE. The second insulating layer covers the luminescent layer and an end surface of the first insulating layer. Since the first insulating layer is not formed by ALE, the device can be manufactured with high productivity, and there is no less of performance compared to a device having two ALE insulation layers.
