Abstract
A light-absorbing composition according to the present invention includes: a light absorber; a curable resin; and an alkoxysilane. The alkoxysilane includes a dialkoxysilane. Since the alkoxysilane of the light-absorbing composition includes the dialkoxysilane, desired flexibility is likely to be imparted to a light-absorbing layer owing to an organic functional group of the dialkoxysilane while a strong skeleton having a siloxane bond is formed in the light-absorbing layer.
