It is obvious that the described embodiments are a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

实施例一 本发明实施例提供一种偏 目位延迟薄膜 1 ,如图 1所示， 该偏 目位 延迟薄膜 1包括：  Embodiment 1 An embodiment of the present invention provides a biasing retardation film 1 . As shown in FIG. 1 , the offset retardation film 1 includes:
呈条状的第一液晶区域 11、 第二液晶区域 12、 以及位于所述第一液晶 区域 11和第二液晶区域 12之间的吸光区域 13; 其中， 所述第一液晶区域 11具有正四分之一波长的相位补偿功能， 所 述第二液晶区域 12具有负四分之一波长的相位补偿功能，所述吸光区域 13 具有吸收入射光的功能。  a stripe-shaped first liquid crystal region 11, a second liquid crystal region 12, and a light absorbing region 13 between the first liquid crystal region 11 and the second liquid crystal region 12; wherein the first liquid crystal region 11 has a positive fourth A phase compensation function of one wavelength, the second liquid crystal region 12 has a phase compensation function of a negative quarter wavelength, and the light absorption region 13 has a function of absorbing incident light.
由于第一液晶区域 11具有正四分之一波长的相位补偿功能， 第二液晶 区域 12具有负四分之一波长的相位补偿功能， 因此， 线偏振光在经过第一 液晶区域 11和第二液晶区域 12之后， 形成左旋偏振光和右旋偏振光。 而 位于第一液晶区域 11和第二液晶区域 12之间的吸光区域 13可以将入射的 线偏振光吸收， 阻挡线偏振光透过吸光区域 13。 Since the first liquid crystal region 11 has a phase compensation function of a positive quarter wavelength, the second liquid crystal The region 12 has a phase compensation function of a negative quarter wavelength, and therefore, the linearly polarized light forms left-handed polarized light and right-handed polarized light after passing through the first liquid crystal region 11 and the second liquid crystal region 12. The light absorbing region 13 located between the first liquid crystal region 11 and the second liquid crystal region 12 can absorb incident linearly polarized light and block linearly polarized light from passing through the light absorbing region 13.
在本发明的优选实施例中， 吸光区域 13包括液晶层， 该液晶层具有二 分之一波长的相位补偿功能。 然而， 本发明中的吸光区域 13不限于此， 可 以是能够吸收入射光， 并阻挡入射光透过的任意吸光区域。 比如， 吸光区 域 13可以是由例如黑色的树脂制成， 从而利用黑色的树脂来实现对光的吸 收。 当该偏振相位延迟薄膜 1运用在 3D显示面板上时， 第一液晶区域 11 对应 3D显示面板的左眼（或右眼） 图像区域， 第二液晶区域 12对应 3D 显示面板的右眼（或左眼） 图像区域。 由于在相邻的右眼图像区域和左眼 图像区域的相接处附近的光最有可能造成图像串扰现象， 而位于第一液晶 区域 11和第二液晶区域 12之间的吸光区域 13可以将右眼图像区域和左眼 图像区域的相接处附近的部分光吸收， 因此上述布置可以防止图像串扰现 象的出现。  In a preferred embodiment of the invention, the light absorbing region 13 comprises a liquid crystal layer having a phase compensation function of one-half wavelength. However, the light absorption region 13 in the present invention is not limited thereto, and may be any light absorption region capable of absorbing incident light and blocking transmission of incident light. For example, the light absorbing region 13 may be made of, for example, black resin to absorb light by using a black resin. When the polarization phase retardation film 1 is applied to a 3D display panel, the first liquid crystal region 11 corresponds to a left eye (or right eye) image region of the 3D display panel, and the second liquid crystal region 12 corresponds to a right eye of the 3D display panel (or left) Eye) Image area.
