In the second embodiment, the average particle diameter of the two light-transmitting particles is preferably 1 to ♦ ♦ The average particle size of the light-transmitting particles is 丨#. In the case of "1", when it is called, it is difficult to form irregularities on the anti-glare layer, so the anti-glare property is lowered, and when it exceeds 1 〇 (4), the surface of the anti-glare layer becomes rough.

When the above-mentioned diffuse reflectance is multiplied by the haze, the value range thereof is less than 0.1 day. Because the anti-glare property is weak, there is a problem that glare of external light cannot be prevented, and 4 «fc/v C Λ Ο·田When it is greater than 5.0, it causes a problem that the scattering is severe and the blackness is lowered. The diffuse reflectance is measured by an ISO standard d/8 and a structure (diffusion using an 8 degree illuminating method), and the light source is used from a pulsed xenon lamp (D65) and a 6-inch integrating sphere from 36 〇 nm to 74. 〇nm is a reflection of the reflectance at intervals of i〇nm, and the diffuse reflectance obtained by converting the reflectance measured according to the above wavelength into the Y value calculated by CIE1931 As long as the diffuse reflectance measuring instrument used in the art is used, it can be easily measured. Further, the above haze can be measured by a haze meter which is generally used in the art.
