Abstract
A photosensitive resin film having a thickness T in μm is provided. When the photosensitive resin film is characterized by ultraviolet-visible spectroscopy, a resulting spectrum has an absorbance A355 at 355 nm, and 0.003<A355/T≤0.03. The spectrum has at least one point within a first wavelength range where the first derivative equals 0 and the second derivative is less than 0, and the point each independently has an Aw1/T value, wherein w1 represents corresponding wavelength of the point, Aw1 represents a corresponding absorbance, and 0.003≤Aw1/T. The first wavelength range is from greater than 450 nm to 780 nm, and the thickness T ranges from 20 μm to 200 μm.
