Abstract: a first light-emitting element and a second light-emitting element that have a resonance structure that causes output light from a light-emission functional layer to resonate between a reflective layer and a semi-transmissive reflective layer, and a pixel definition layer, and in which an aperture part is formed to correspond to each of the first light-emitting element and the second light-emitting element, are formed on a base. a first interval between the reflective layer and the semi-transmissive reflective layer in the first light-emitting element and a second interval between the reflective layer and the semi-transmissive reflective layer in the second light-emitting element are different, and a film thickness of the pixel definition layer is less than a difference between the first interval and the second interval.

Abstract: a piezoelectric substrate according to the present disclosure includes: a base body; an electrode formed at the base body; and a piezoelectric layer formed at the electrode and containing potassium, sodium, and niobium. a value of irir obtained by dividing an integrated intensity ir at a peak by an integrated intensity ir at a peak when a surface of the piezoelectric layer is measured by fourier transform infrared spectroscopy, is less than 0.086. here, the peak has a strongest area intensity among peaks detected at wavenumbers of 475 cmto 700 cm, and the peak has an area intensity that is a sum of area intensities of peaks detected at wavenumbers of 1200 cmto 1645 cm.
