摘要： Provided is a thermal distribution display including, on a support, a thermal distribution display layer which includes an organic polymer composite containing an electron-donating dye precursor and a polymer; at least an electron-accepting compound A represented by the following formula (1) and an electron-accepting compound B represented by the following formula (2); and a binder, wherein the content ratio (A : B) is from 95 : 5 to 50 : 50 on a mass basis, and the content of the electron-accepting compound A in the total amount of electron-accepting compounds is 40% by mass or greater: wherein, in the formula (1), each of R 1 to R 4 independently represents a hydrogen atom, a halogen atom, an amino group, or the like; M represents a metal atom having a valency of n; and n represents an integer from 1 to 3; and wherein, in the formula (2), each of R 1 to R 10 independently represents a hydrogen atom, a halogen atom, a hydroxy group, or the like, at least one of them being a hydroxy group; and X represents -S-, -SO 2 -, -SO 2 NH-, or -OCH 2 CH 2 O-.
