摘要

本发明提供一种触控面板，其能赋予防眩性等的诸特性，同时能防止画素密度300ppi以上的超高精细之显示元件的映像光之眩目。;一种触控面板，其系具有光学薄片作为构成构件之触控面板，其中前述光学薄片系在表面具有凹凸形状，同时前述凹凸形状满足自下述(A)~(C)选出的至少一个条件，且前述触控面板系使用于画素密度300ppi以上的显示元件之前面；条件(A)：显示前述凹凸形状之倾斜角度分布曲线的峰值之1/2值的倾斜角度之间隔为5~15度，条件(B)：自显示前述凹凸形状之倾斜角度分布曲线的峰值之倾斜角度起，显示在正方向之反曲点之倾斜角度为4~15度，而且显示前述在正方向之反曲点的倾斜角度与显示前述倾斜角度分布曲线之峰值的倾斜角度之差为2.2~10度，条件(C)：显示前述凹凸形状之倾斜角度分布曲线的峰值之倾斜角度为2~8度，而且前述凹凸形状的倾斜角度分布之歪度为0~1.5及/或前述凹凸形状的倾斜角度分布之峭度为1.5~6。;The touch panel includes an optical sheet as a component, in which the optical sheet has an uneven shape on a surface, the uneven shape satisfies at least one condition selected from the following (A) to (C), and the touch panel is used for a front surface of a display element having a pixel density of 300 ppi or more, Condition (A); a gap between inclination angles indicating a half value of a peak value of an inclination angle distribution curve of the uneven shape is in a range of 5 degrees to 15 degrees, Condition (B); an inclination angle indicating an inflection point on a positive direction side of the inclination angle indicating the peak value of the inclination angle distribution curve of the uneven shape is in a range of 4 degrees to 15 degrees, and a difference between the inclination angle indicating the inflection point on the positive direction side and the inclination angle indicating the peak value of the inclination angle distribution curve is in a range of 2.2 degrees to 10 degrees, and Condition (C); the inclination angle indicating the peak value of the inclination angle distribution curve of the uneven shape is in a range of 2 degrees to 8 degrees, skewness of the inclination angle distribution curve of the uneven shape is in a range of 0 degrees to 1.5 degrees, and/or kurtosis of the inclination angle distribution curve of the uneven shape is in a range of 1.5 to 6.
