摘要:
The invention aims to provide a light emitting device comprising a base material or protective member which has improved light transmittance, heat resistance, passivation (gas barrier, oligomer release prevention and minimized outgassing), anti-water or moisture-absorption, stability against chemical degradation, dimensional and shape stability, anti-surface-reflection, electrical insulation, UV degradation resistance, and weather resistance, and is highly productive due to possible film formation under atmospheric pressure, and hence, a light emitting device featuring high reliability, ease of manufacture and low cost. The object is attained by a light emitting device comprising a base material (1) having flexibility, light transparency and heat resistance, a lower electrode (4) having light transmittance, a light emitting layer (4), and an upper electrode (4) formed on the base material, the device further comprising a silica film and/or a siliceous film (3) which is formed on the substrate side as viewed from the light emitting layer (4) or on opposite sides of the substrate by applying polysilazane and subjecting it to oxidative treatment.
