    摘要： An optical sheet for enhancing contrast ratio, a filter including the same, and an image display device including the optical sheet or the filter. The optical sheet includes: a light transmission portion including a plurality of grooves disposed at predetermined intervals in an end portion of the light transmission portion on one side; and a plurality of external light absorption portions each disposed in said each groove and comprising a composition completely or incompletely filling the groove, the composition comprising a light absorbable material, wherein at least one of the grooves comprises a recess portion formed on the top of the external light absorption portion. When used in the image display device, the optical sheet and the filter including the optical sheet can achieve a relatively high light transmission rate, prevent formation of ghost images, prevent the occurrence of the Moire phenomenon, and achieve a relatively high contrast ratio to maintain high resolution.

    摘要： Provided are an optical sheet for high resolution, a filter comprising the same, and a display device having the optical sheet for high resolution or the filter. The optical sheet for high resolution includes: a plurality of external light absorption units that are disposed separate from each other at a predetermined interval and comprise a light absorbing material; a plurality of light transmission units optically separated from each other by the external light absorption units, wherein the refractive index of the light transmission unit is smaller than the refractive index of the external light absorption unit. Thus, the optical sheet for high resolution, the filter comprising the same, and the display device having the optical sheet for high resolution or the filter can maintain high resolution by reducing generation of ghost images and moiré phenomenon and improving the contrast ratio.
