Display apparatus and method for producing same

摘要

A display apparatus includes a pair of substrates connected to each other via a pre-set gap for delimiting a hermetically sealed space, an ionizable gas charged into this space, and discharging electrodes formed at least on one of the substrates to incur discharge in the space. The discharging electrodes are coated with a protective skin film formed by the electro-deposition method. The protective skin film is an electro-deposited and sintered mixture of boride or carbon containing electrically conductive powders and glass powders. In electro-deposition, the mean particle size of the electrically conductive powders and the glass powders is not larger than 10 mum or in a range from 1 to 3 mum. The electrically conductive powders and the glass powders are mixed in a volumetric ratio in a range from 9:1 to 3:7, with the film thickness of the protective skin film being in a range from 1 to 20 mum. This enables suppression of deterioration of the discharging electrodes with lapse of time, while enabling the lowering of the discharge voltage.
