A light control sheet (10) of the present invention includes an adhesive layer (11) attached to a transparent material (TM), and a light control layer (12) attached to the transparent material (TM) via the adhesive layer (11), the light control layer (12) having a transparent state or an opaque state depending on whether a voltage is applied to the light control layer (12). At least one of the adhesive layer (11) and the light control layer (12) includes a filter absorbing part of light in the visible region. Transmittance is 10% or less for light with a wavelength range of 420 nm or less passing through the light control window from the light control sheet (10) toward the transparent material (TM) in a first direction (D1), and light from a standard light source D65 passing through the light control window from the transparent material (TM) toward the light control sheet (10) in a second direction (D2) has a yellowness index YI of 10 or less according to JIS K 7373: 2006.
