Abstract:
A laminated film having a haze of 1.0% or less and including two kinds of silica particles (silica particles A and silica particles B) in a cured layer, wherein the occupied area proportion of the silica particles A on a cross-sectional TEM image of the cured layer is 0.5% to 20.0% and satisfies the following relationship with the occupied area proportion of the silica particles B: 0.005≤occupied area proportion of silica particles A/occupied area proportion of silica particles B≤0.400, the variation coefficient of the occupied area proportion of the silica particles A on the cross-sectional TEM image of the cured layer is more than 0.5% and 3.0% or less, and the variation coefficient of the occupied area proportion of the silica particles B is 0.0% to 0.5%; a production method thereof; a polarizing plate; a liquid crystal panel; a liquid crystal display; and a touch panel.
