Electron excited luminous element with an anode substrate having a glass exposed subface provided with a hydrophobic property

An electron excited luminous element comprising:

• a vacuum airtight envelope constructed of at least a cathode substrate made of glass and provided thereon with an electron emission means and an anode substrate made of glass and arranged opposite to said cathode substrate;
• said anode substrate being provided thereon with stripe-like anode electrodes;
• said stripe-like anode electrodes being provided thereon with phosphor layers which are excited by electrons emitted from said electron emission means;
• said anode substrate being provided at only a portion thereof in proximity to said anode electrodes and irradiated with electrons with a hydrophobic property.
