液晶显示装置
摘要：
本发明提供一种TN型液晶显示装置(1)，其从观察面依次配置偏振板(4a)、液晶面板(100)、偏振板(4b)而构成，其按照第一基板(2a)和第二基板(2b)各自的摩擦方向(6a，6b)与偏振板(4a，4b)的吸收轴(4α，4β)所成的角度在各基板(2a，2b)中分别设定为约45度，并且该吸收轴(4α，4β)相互正交的方式进行配置。并且，例如，至少在上述基板(2a)和偏振板(4a)之间，配置有按照该偏振板(4a)的吸收轴(4α)与面内滞相轴(5α)形成为约90度的方式进行设计的双轴性相位差板(5a)。由此，可以以低成本实现同时达成改善TN型显示模式的液晶显示装置的视野角显示特性和材料部件的利用效率的技术。
摘要（英）：

Disclosed is a TN liquid crystal display device (1) wherein a polarizing plate (4a), a liquid crystal panel (100) and a polarizing plate (4b) are sequentially arranged from the viewer side. In the TN liquid crystal display device (1), the rubbing directions (6a, 6b) of a first substrate (2a) and a second substrate (2b) are respectively set at an angle of about 45 DEG relative to absorption axes (4a, 4beta) of the polarizing plates (4a, 4b), and the absorption axes (4a, 4beta) are so arranged as to be perpendicular to each other. Additionally, for example, a biaxial retardation plate (5a), which is so designed as to have an in-plane slow axis (5a) at an angle of about 90 DEG relative to the absorption axis (4a) of the polarizing plate (4a), is interposed between the substrate (2a) and the polarizing plate (4a). Consequently, a TN liquid crystal display device having improved viewing angle characteristics and utilization efficiency of component members can be obtained at low cost.
