Disclosed is a thermal distribution display comprising a base and a thermal distribution display layer arranged on the base, wherein the thermal distribution display layer comprises an organic polymeric complex comprising an electron-donating dye precursor and a polymer, at least an electron-accepting compound (A) represented by general formula (1) and an electron-accepting compound (B) represented by general formula (2), and a binder, in which the content ratio (A:B) is 95:5 to 50:50 by mass and the content of the compound (A) is 40% by mass or more relative to the total mass of the electron-accepting compounds. [In general formula (1), R1 to R4 independently represent 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 of 1 to 3.] [In general formula (2), R1 to R10 independently represent a hydrogen atom, a halogen atom, a hydroxy group, or the like, wherein at least one of R1 to R10 represent a hydroxy group; and X represents -S-, -SO2-, -SO2NH- or -OCH2CH2O-.] |
