Abstract:
A lamination sheet includes a first layer, a second layer, and a third layer. The first layer is a layer made of resin and having optical transparency. The second layer is a layer made of resin and provided on the back side of the first layer. The third layer is a layer made of resin and provided on the back side of the second layer. The first layer is a layer, the thickness of which 188 μm or larger. The second layer is a patterned layer. The third layer is a layer, the thermal resistance value of which is higher than the thermal resistance value of the second layer.
