Title (EN) FRONT PLATE FOR ONBOARD LCD DEVICE
(FR) PLAQUE AVANT POUR DISPOSITIF LCD EMBARQUÉ
(JA) 車載用液晶表示装置の前面板
Abstract:
(EN) The present invention can provide a front plate for an onboard LCD device, the front plate being characterized by comprising a layer containing a high-hardness resin composition (B) on at least one side of a layer containing a resin (A) that contains a polycarbonate resin (a1), having a raised-and-recessed hard coating layer on the layer containing the high-hardness resin composition (B), and satisfying the following conditions (i) to (iv). (i) The thickness of the layer containing the high-hardness resin composition (B) is 10–250 μm, and the total thickness of the layer containing the resin (A) that contains the polycarbonate resin (a1) and the layer containing the high-hardness resin composition (B) is 100–3,000 μm. (ii) The high-hardness resin composition comprises any one of specific resin compositions (B1) to (B3). (iii) The front plate has a retardation of at least 3,000 nm. (iv) The standard deviation of the second derivative of the raised-and-recessed shape of the raised-and-recessed hard coating layer is at least 0.1.
(FR) L'invention concerne une plaque avant pour un dispositif LCD embarqué, la plaque avant étant caractérisée en ce qu'elle comprend une couche contenant une composition de résine à dureté élevée (B) sur au moins un côté d'une couche contenant une résine (A) qui contient une résine de polycarbonate (a1), en ce qu'elle comporte une couche de revêtement dure surélevée et évidée sur la couche contenant la composition de résine à dureté élevée (B), et en ce qu'elle satisfait aux conditions (i) à (iv) suivantes. (i) L'épaisseur de la couche contenant la composition de résine à dureté élevée (B) est de 10 à 250 µm, et l'épaisseur totale de la couche contenant la résine (A) qui contient la résine de polycarbonate (a1) et de ladite couche contenant la composition de résine à dureté élevée (B) est de 100 à 3 000 µm. (ii) Cette composition de résine à dureté élevée comprend n'importe laquelle des compositions de résine spécifiques (B1) à (B3). (iii) La plaque avant présente un retard d'au moins 3 000 nm. (iv) L'écart type de la seconde dérivée de la forme surélevée et évidée de la couche de revêtement dure surélevée et évidée est d'au minimum 0,1.
(JA) 本発明によれば、ポリカーボネート樹脂(a1)を含む樹脂(A)を含む層の少なくとも一方の面に、高硬度樹脂組成物(B)を含む層を有し、更に、該高硬度樹脂組成物(B)を含む層上に、凹凸を有するハードコート層を有し、下記条件(i)から(iv)を満たすことを特徴とする車載用液晶表示装置の前面板を提供することができる。 (i)前記高硬度樹脂組成物(B)を含む層の厚みが10~250μmであり、前記ポリカーボネート樹脂(a1)を含む樹脂(A)を含む層と前記高硬度樹脂組成物(B)を含む層との合計厚みが100~3,000μmであり、 (ii)前記高硬度樹脂組成物(B)が特定の樹脂組成物(B1)から(B3)のいずれか1つからなり、 (iii)前記前面板のレターデーションが3,000nm以上であり、 (iv)前記凹凸を有するハードコート層の凹凸形状の2回微分の標準偏差が0.1以上である。
