Abstract

The invention provides a method for manufacturing a dual-view liquid crystal display. Firstly, a substrate is provided, and the substrate has a first surface and a second surface opposite to each other. Next, a barrier layer is formed on the first surface of the substrate, wherein the barrier layer has a plurality of light-transmitting openings. Then, a thinning process is performed on the substrate via the second surface of the substrate. Then, the liquid crystal display panel is bonded to the second surface of the substrate, wherein the liquid crystal display panel and the barrier layer simultaneously transmit the first light and the second light to the first observer and the second observer respectively. The invention combines the barrier layer and the liquid crystal display panel with the substrate, and the realized dual-view liquid crystal display has uniform thickness, better process yield and better display quality.

Description

【Technical field】 [0001] The invention relates to a manufacturing method of a liquid crystal display, and in particular to a manufacturing method of a dual-view liquid crystal display. 【Background technique】 [0002] Due to the characteristics of power saving and small size, liquid crystal displays have been further applied to car TVs and car GPS (Global Positioning System, GPS) in recent years to watch programs and display driving maps. However, when driving with a GPS system, passengers cannot watch the show. In order to solve this problem, a dual-view liquid crystal display (dual-view LCD) has emerged as the times require. [0003] figure 1 It is a partial cross-sectional schematic diagram of an existing dual-view liquid crystal display. Please refer to figure 1 , the dual-view liquid crystal display 100 includes a color filter substrate 110 , an active device array substrate 120 and a liquid crystal layer 130 . The liquid crystal layer 130 is disposed between the co...
