摘要:
In an image display apparatus, each sub-pixel includes a phosphor configured to emit light of a predetermined color when the phosphor is irradiated with electrons, an electron emission device configured to irradiate the phosphor with the electrons, and a resistor connected in series to the electron emission device and having a negative temperature characteristic of resistance. In three or more sub-pixels with different luminescent colors included in each pixel, the resistor is configured such that a sub-pixel having a phosphor with a smaller temperature dependency of luminescent brightness has a resistor with a greater activation energy, or the resistor is configured such that the resistor is made of the same material for the three or more sub-pixel and such that a sub-pixel having a phosphor with a smaller temperature dependency of luminescent brightness has a resistor with a greater resistance.
