High resolution sheet and filter comprising the same, and display device having the sheet or the filter

摘要

High resolution sheet, a filter, and a display device having the sheet or filter is disclosed for having the same. High resolution disclosed sheet is disposed spaced apart from each other at predetermined intervals, a plurality of external light-absorbing portion containing a black light absorbing material; By the external light absorption unit comprising: a plurality of light transmitting portions spaced apart from each other optically, characterized in that the refractive index of the light transmission portion is smaller than the refractive index of the external light-absorbing portion. ; Thus, by the disclosed high-resolution sheet filter with this, and the display device having the sheet or the filter is reduced and the dual phase formation moire improve the contrast ratio it can be maintained for high resolution.
