Abstract:
(EN) The present invention provides: an organic electroluminescence display device that better suppresses reflection of external light when viewed obliquely; a phase difference film; and a circularly polarizing plate. This organic electroluminescence display device has: an organic electroluminescence display panel; and a circularly polarizing plate that is arranged on the organic electroluminescence display panel. The circularly polarizing plate has a polarizer and a phase difference film. The phase difference film has, from the polarizer side, a negative A plate and a positive A plate. The in-plane retardation of the negative A plate at a wavelength of 550 nm is greater than 50 nm but no greater than 90 nm. The in-plane retardation of the positive A plate at a wavelength of 550 nm is 100–200 nm. The angle formed by the in-plane slow axis of the negative A plate and the in-plane slow axis of the positive A plate is 45±10°.
(FR) La présente invention concerne : un dispositif d'affichage électroluminescent organique qui supprime mieux la réflexion de la lumière extérieure lorsqu'on l'observe de biais ; un film à différence de phase ; et une plaque de polarisation circulaire. Ce dispositif d'affichage électroluminescent organique comporte : un panneau d'affichage électroluminescent organique ; et une plaque de polarisation circulaire qui est disposée sur le panneau d'affichage électroluminescent organique. La plaque de polarisation circulaire comporte un polariseur et un film à différence de phase. Le film à différence de phase comporte, à partir du côté polariseur, une plaque A négative et une plaque A positive. Le retard dans le plan de la plaque A négative à une longueur d'onde de 550 nm est supérieur à 50 nm mais inférieur ou égal à 90 nm. Le retard dans le plan de la plaque A positive à une longueur d'onde de 550 nm est de 100 à 200 nm. L'angle formé par l'axe lent dans le plan de la plaque A négative et l'axe lent dans le plan de la plaque A positive est de 45 ± 10°.
(JA) 本発明は、斜め方向から視認した際の外光反射がより抑制された、有機エレクトロルミネッセンス表示装置、並びに、位相差フィルムおよび円偏光板を提供する。本発明の有機エレクトロルミネッセンス表示装置は、有機エレクトロルミネッセンス表示パネルと、有機エレクトロルミネッセンス表示パネル上に配置された円偏光板とを有する、有機エレクトロルミネッセンス表示装置であって、円偏光板が、偏光子と位相差フィルムとを有し、位相差フィルムが、偏光子側から、ネガティブAプレートおよびポジティブAプレートを有し、ネガティブAプレートの波長550nmにおける面内レタデーションが50nm超90nm以下であり、ポジティブAプレートの波長550nmにおける面内レタデーションが100~200nmであり、ネガティブAプレートの面内遅相軸とポジティブAプレートの面内遅相軸とのなす角度が45±10°である。
