Abstract: A method for positioning a phase retarder substrate includes the following steps. A phase retarder substrate is provided, wherein the phase retarder substrate includes a first align mark which includes a patterned phase retarder film. An image capturing unit is disposed at one side of the phase retarder substrate. A light source is disposed at the other side of the phase retarder substrate. An upper polarizing sheet is disposed between the image capturing unit and the patterned phase retarder film, and a lower polarizing sheet is disposed between the light source and the patterned phase retarder film. An image of the light which passes through the lower polarizing sheet, the patterned phase retarder film and the upper polarizing sheet is captured so as to position the phase retarder substrate.

Abstract: A three-dimensional imaging device is provided which includes a display device and a viewing device. The display device includes a first substrate, a second substrate, a black absorbing layer and a cholesteric liquid crystal layer including a first levo-cholesteric liquid crystal layer and a first dextro-cholesteric liquid crystal layer. The viewing device includes a second levo-cholesteric liquid crystal layer and a second dextro-cholesteric liquid crystal layer. The first levo-cholesteric liquid crystal layer is made of a same material as the second levo-cholesteric liquid crystal layer, and the first dextro-cholesteric liquid crystal layer is made of a same material as the second dextro-cholesteric liquid crystal layer.

Abstract: A TFT array substrate including a substrate, a plurality of pixel structures and a plurality of cutting marks is provided. The substrate has a device region and a cutting mark region. The pixel structures are disposed in the device region and each pixel structure includes a TFT, a pixel electrode and a passivation layer covering the TFT. The cutting marks are within the cutting mark region, disposed at two sides of a predetermined cutting position, and are arranged as a row or column perpendicular to a predetermined cutting direction. In particular, the cutting marks are constituted of at least two colors, at least two shapes, at least one color and at least one shape, or a combination thereof.

Abstract: A display device has a display panel that is divided into an active region for displaying images and a dummy region outside of the active region. The display device comprises a first substrate and a second substrate disposed in parallel and spaced apart from each other; a plurality of electrical conductive structures disposed on the first substrate and located within the dummy region; and a transparent conducting layer disposed on the second substrate and disposed over both the active region and the dummy region, the transparent conducting layer being utilized for providing a fixed voltage, wherein the transparent conducting layer in the dummy region has an empty area facing at least one electrical conductive structure. The empty area is formed by removing a conducting material of the transparent conducting layer. Parasitic capacitances in display device can be reduced.
