A stereoscopic display device is disclosed. The stereoscopic display device includes a backlight module, a first liquid crystal display panel, a first polarizer, a second liquid crystal display panel, a second polarizer, and a detachable polarizer. The backlight module has a light emitting side. The first polarizer, the first liquid crystal display panel, the detachable polarizer, the second liquid crystal display panel, and the second polarizer are disposed sequentially from the light emitting side. The detachable polarizer is detachably inserted. By designing arrangements of the first polarizer, the second polarizer, and the detachable polarizer, and by limiting the pixel scale relationship between the first liquid crystal display panel and the second liquid crystal display panel, various types of stereoscopic display technologies can be implemented according to the present invention.

Stereoscopic display device

A color filter substrate having a substrate, a black matrix layer, a first filter layer and a second filter layer is provided. The black matrix layer is disposed on the substrate, and multiple pixel areas is defined on the substrate by the black matrix layer. Each pixel area includes a first sub-pixel area and a second sub-pixel area. The first and second filter layer are disposed in the pixel area, and the second filter layer covers the first filter layer. A refractive index of the second filter layer is greater than that of the first filter layer, such that light emitting direction of the first sub-pixel area is different from that of the second sub-pixel area. Besides, a fabricating method of the color filter substrate and an LCD panel with the color filter substrate are provided. The LCD panel with 3D image display or dual-view function can be easily manufactured.

Color filter substrate and fabricating method thereof and liquid crystal display panel

An examining device adapted to examining a transmittance of a display panel is provided. The examining device includes a light source, a first polarizer, a photodetector, a second polarizer, at least one first reflector and at least one second reflector. The light source and the photodetector are respectively disposed on both sides of the display panel. The second polarizer is disposed between the display panel and the photodetector. The first reflector is disposed between the display panel and the second polarizer. The second reflector is disposed between the display panel and the first polarizer. Light emitting from the light source successively passes via the first polarizer, the display panel, the first reflector, the display panel, the second reflector, the display panel, the second polarizer and then emits into the photodetector.
