Interlayer film structure for laminated panel, and laminated panel structure

An interlayer film structure comprising:

• a first light-modulating film capable of switching between light transmission and light scattering;
• and
• a second light-modulating film capable of adjusting a visible light transmittance,
• wherein:
• the first light-modulating film and the second light-modulating film are arranged in a thickness direction;
• a solar direct transmittance (Tds) configured to be measured in the first light-modulating film in a light-transmission mode, in a laminated panel structure obtained by bonding two sheets of clear glass having a thickness of 2.5 mm with the interlayer film structure interposed therebetween, is adjustable to 55% or less;
• and
• a haze value configured to be measured in the first light-modulating film in the light-transmission mode, in the laminated panel structure obtained by bonding the two sheets of clear glass having the thickness of 2.5 mm with the interlayer film structure interposed therebetween, is adjustable to 40% or less.
