Abstract:
1. An image display apparatus comprising a plurality of pixels each including three or more sub-pixels having different luminescent colors, the pixels being configured such that: 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, the temperature dependency of luminescent brightness of the phosphor and the activation energy of the resistor are different among the three or more sub-pixels with different luminescent colors included in each pixel, and in the three or more sub-pixels with different luminescent colors included in each pixel, a sub-pixel having a phosphor with a smaller temperature dependency of luminescent brightness has a resistor with a greater activation energy.
