20140209895 | ARRAY SUBSTRATE, FABRICATION METHOD THEREOF AND DISPLAY DEVICE - The invention provides an array substrate, a fabrication method thereof and a display device. The array substrate comprises a base substrate; a gate layer which is disposed on the base substrate and comprises a gate; a gate insulating layer disposed on the gate layer; a source layer which is disposed on the gate insulating layer and comprises a source; a metal oxide semiconductor layer which is disposed on the source layer and the gate insulating layer and comprises an active layer, wherein the source is in direct contact with the active layer; and a pixel electrode layer in direct contact with the active layer. A position where the gate is formed in the gate layer corresponds to a position between the source and a contacting portion of the pixel electrode layer with the active layer. | 07-31-2014 |

20150370126 | LIQUID CRYSTAL DISPLAY APPARATUS - A liquid crystal display device includes a liquid crystal panel, a polaroid for polarizing light positioned on a light incident side of the liquid crystal panel, and a polarization analyzer positioned on a light emission side of the liquid crystal panel. The polarization analyzer includes a transparent plate. The transparent plate being arranged at a set angle with a light emission surface of the liquid crystal panel, such that the transparent plate analyzes polarization of light emitted from the light emission surface of the liquid crystal panel. Because the polaroid is used only on the light incident side of the liquid crystal panel, while the transparent plate is used instead of a polaroid on the light emission side of the liquid crystal panel,a reduction in the material cost of the liquid crystal display device can be achieved. | 12-24-2015 |
