技术领域technical field

本发明涉及立体图像显示设备，特别涉及将由于观看者所看到的左右图像之间的串扰而引起的图像质量恶化减到最低程度、并具有增强的亮度和孔径比的立体图像显示面板和包括该立体图像显示面板的立体图像显示设备。The present invention relates to a stereoscopic image display device, and in particular to a stereoscopic image display panel which minimizes deterioration of image quality due to crosstalk between left and right images seen by a viewer and has enhanced brightness and aperture ratio and comprises The stereoscopic image display device of the stereoscopic image display panel.

背景技术Background technique

随着信息社会的发展，市场正在需求显示设备的增大和纤薄化。由于这种需求，对于纤薄、重量轻、功耗低的各种平板显示设备的要求正在迅速增长。With the development of the information society, the market is demanding enlargement and slimming of display devices. Due to this demand, demands for various flat panel display devices that are slim, light in weight, and low in power consumption are rapidly increasing.

作为平板显示设备，正在积极研究液晶显示设备(LCD)、等离子显示面板(PDP)、场致发射显示设备(FED)和发光二极管显示设备(LED)。然而，在这些平板显示设备之中，LCD由于其各种优点而被广泛使用，例如大规模生产的技术发展、结构和驱动器的驱动简易、低功耗以及实现高质量图像。As flat panel display devices, liquid crystal display devices (LCD), plasma display panels (PDP), field emission display devices (FED), and light emitting diode display devices (LED) are being actively researched. However, among these flat panel display devices, LCDs are widely used due to various advantages such as technical development of mass production, easy driving of structure and drivers, low power consumption, and realization of high-quality images.

近来，正在开发使观看者能够在其中显示的二维(2D)图像中观看到具有立体感的三维(3D)图像的立体图像显示设备。Recently, a stereoscopic image display device that enables a viewer to view a three-dimensional (3D) image with a stereoscopic feeling in a two-dimensional (2D) image displayed therein is being developed.

立体图像显示设备将图像分离为具有双目视差的左右图像，以便为观看者的左眼显示左图像，而为观看者的右眼显示右图像。也就是说，立体图像显示设备允许观看者的左眼仅仅看到左图像，而观看者的右眼仅仅看到右图像，由此使观看者能够观看到具有立体感的3D图像。A stereoscopic image display device separates images into left and right images with binocular disparity, so that the left image is displayed for the viewer's left eye and the right image is displayed for the viewer's right eye. That is, the stereoscopic image display device allows the viewer's left eye to see only the left image, and the viewer's right eye to see only the right image, thereby enabling the viewer to view a 3D image with a stereoscopic effect.

然而，在现有技术的立体图像显示设备中，会发生这样的情况：尽管要求的是观看者的左眼仅仅看到左图像而观看者的右眼仅仅看到右图像，但观看者的右眼会看到左图像，或观看者的左眼会看到右图像。现有技术的立体图像显示设备存在由于左图像和右图像之间的串扰而损害图像质量的局限性。However, in the stereoscopic image display device of the prior art, such a situation may occur that although it is required that the viewer's left eye sees only the left image and the viewer's right eye sees only the right image, the viewer's right eye will see the left image, or the viewer's left eye will see the right image. The related art stereoscopic image display device has a limitation that image quality is impaired due to crosstalk between left and right images.
