Patent ID: 7329978

Claim:
A cold cathode field emission display comprising a cathode panel having a plurality of cold cathode field emission devices and an anode panel which panels are bonded to each other in their circumferential portions, the anode panel comprising a substrate, a phosphor layer formed on the substrate, an anode electrode formed on the phosphor layer and a resistance layer for controlling a discharge current, the resistance layer being formed on the anode electrode and having a thickness of t R (unit: μm), and the cold cathode field emission display satisfying the following expression (1), Q >(½) C·V A 2 (1) where Q ≈ π · t R · r R 2 · d R × [ C m_S ⁡ ( T L - T r ) + Q S_L + C m_L ⁡ ( T G - T L ) + Q L_G ] × 10 - 6 and, C: an electrostatic capacity (F) between the cold cathode field emission device and the anode electrode, V A : a voltage (V) to be applied to the anode electrode, r R : a radius (mm) of a vaporization-allowable region of the resistance layer, d R : a density (g·cm −3 ) of a material constituting the resistance layer, C m — S : a specific heat (J·g −1 ·K −1 ) of a material constituting the resistance layer in a solid state, T L : a melting point (° C.) of a material constituting the resistance layer, T r : room temperature (° C.), Q S — L : a heat of solution (J·g −1 ) of a material constituting the resistance layer, C m — L : a specific heat (J·g −1 ·K −1 ) of a material constituting the resistance layer in a liquid state, T G : a boiling point (° C.) of a material constituting the resistance layer, and, Q L — G : a heat of vaporization (J·g −1 ) of a material constituting the resistance layer.
