• wherein the energy beam-curable composition comprises a silicone resin component represented by the following average unit formula 1,
• (R13SiO1/2)a(R22SiO2/2)b(R3SiO3/2)c(SiO4/2)d(RO1/2)e [Average Unit Formula 1]
• wherein, R1 to R3 are each independently a hydrogen atom, an alkyl group, an aryl group or an energy beam-curable group, and when R1 to R3 exist plurally, they are each the same or different from each other, and at least one of R1 to R3 is an energy beam-curable group, and when a+b+c+d has been converted to 1, a, b, c and d satisfy 0≤a≤1, 0<b≤1, 0<c≤1 and 0≤d≤1, respectively, and e is a number in which e/(a+b+c+d) falls within a range of 0 to 0.4, and
• wherein the cured material layer has an uneven surface having a negative skewness according to ISO 25178 standard on at least one side thereof, wherein
