A bioinformation display device is provided with a pulse wave acquiring unit, an index derivation unit, a determination unit (S320, S350, S360), and a display control unit (S330, S340, S370-S400, S420). The pulse wave acquiring unit acquires a pulse wave signal obtained by measuring a pulse wave of a test subject along a time axis. The index derivation unit derives respiratory function indexes which are a plurality of indexes representing states of respiratory function of the test subject. The determination unit determines whether at least one of the derived plurality of respiratory function indexes is in a prescribed range prescribed in advance as a range of threshold values representing a deterioration in the health condition of the test subject. When at least one of the plurality of respiratory function indexes is in the prescribed range, the display control unit displays progress information indicating progress of the plurality of respiratory function indexes since attaining of the prescribed range by the at least one of the plurality of respiratory function indexes.
