A decorative sheet, a cover panel, a display device, a method for manufacturing a decorative sheet, and a method for manufacturing a cover panel.

Abstract

The present invention provides a display device in which micro-holes are difficult to see even when the light source is not illuminated, a decorative sheet and cover panel used in the display device, and a method for manufacturing the decorative sheet and the cover panel. [Solution] The decorative sheet comprises a base film, a design layer, and a color-tuning layer. The design layer is formed by a first ink layer provided on the base film, and a plurality of light-transmitting microholes are formed in the first ink layer. The color-tuning layer is a second ink layer that seals the microholes. The difference Δa* between the chromaticity a* of the first ink layer and the chromaticity a* of the color-tuning layer is between -7 and +7, and the difference Δb* between the chromaticity b* of the first ink layer and the chromaticity b* of the color-tuning layer is between -7 and +7.
