Abstract:
(EN) The present invention provides a display device which does not undergo the formation of interference patterns in both a front direction and an oblique direction. The present invention is a display device comprising a display panel, a front panel arranged in front of the display panel with an air layer interposed therebetween, and a film arranged on the front surface of the display panel or on the back surface of the front panel, wherein the thickness of the air layer is 50 μm or less, the display panel and/or the front panel can be warped, the thickness of the air layer can vary within the range from 0 to 50 μm when the display panel and/or the front panel is warped, the film has a moth eye structure on a surface thereof which contacts with the air layer, and the reflectivity of at least one wavelength falling within the range from 600 to 780 nm inclusive is smaller than the reflectivity at a wavelength of 550 nm in the reflection spectra of 5 degree regular reflection of the moth eye structure.
(FR) La présente invention concerne un dispositif d'affichage qui ne subit pas la formation de motifs d'interférences à la fois dans une direction vers l'avant et dans une direction oblique. La présente invention est un dispositif d'affichage comprenant un panneau d'affichage, un panneau avant disposé devant le panneau d'affichage, une couche d'air étant interposée entre lesdits deux panneaux, et un film disposé sur la surface avant du panneau d'affichage ou sur la surface arrière du panneau avant, l'épaisseur de la couche d'air étant de 50 μm ou moins. Le panneau d'affichage et/ou le panneau avant peuvent être voilés, l'épaisseur de la couche d'air peut varier dans la plage allant de 0 à 50 μm lorsque le panneau d'affichage et/ou le panneau avant sont voilés, le film a une structure d'œil de mite sur sa surface qui est en contact avec la couche d'air, et la réflectivité d'au moins une longueur d'onde située dans la plage comprise entre 600 et 780 nm inclus est inférieure à la réflectivité à une longueur d'onde de 550 nm dans les spectres de réflexion régulière de 5 degrés de la structure d'œil de mite.
(JA) 本発明は、正面方向のみならず斜め方向においても干渉縞の発生を抑制することができる表示装置を提供する。本発明は、表示パネルと、空気層を介して前記表示パネルの前方に配置された前面板と、前記表示パネルの前面又は前記前面板の背面に配置されたフィルムとを備え、前記空気層の厚みは、50μm以下であり、前記表示パネル及び/又は前記前面板は、撓み得るものであり、前記表示パネル及び/又は前記前面板が撓んだ状態で、前記空気層の厚みは、0μm~50μmの範囲で変化し、前記フィルムは、前記空気層に接する面にモスアイ構造を有し、前記モスアイ構造の5度正反射の反射スペクトルにおいて、600nm以上、780nm以下の範囲内の少なくとも1点の波長の反射率は、550nmの反射率よりも小さい表示装置である。
