A liquid crystal display has spacers for maintaining a liquid crystal layer and a cell gap between a substrate and an opposite substrate and also has regions either within a single pixel or over two or more pixels. The spacers are of columnar shape elongated from the substrate to the opposite substrate or the other way round, and the columnar spacers are provided in regions in which the liquid crystal layer is thinnest among those regions in which the liquid crystal layer varies in thickness. The structure makes the liquid crystal display having two or more different cell gaps to stably maintain those cell gaps and produces good quality displays.

Liquid crystal display and manufacturing method thereof

Each pixel region includes a transmission region for display in a transmission mode using light entering through a first substrate and a reflection region for display in a reflection mode using light entering through a second substrate. The first substrate includes a transparent electrode region and a reflection electrode region, both of which have flat surfaces facing a liquid crystal layer. The second substrate includes a transparent electrode in the reflection region and the transmission region on its surface facing the liquid crystal layer and includes a light diffusion layer in the reflection region, and the surface facing the liquid crystal layer is flat in the transmission region and the reflection region.

A method of manufacturing a multi-panel liquid crystal display device prepared by connecting a liquid crystal multi-panel having a plurality of display surfaces to a reinforcing substrate includes the steps of: (a) forming a pattern of a seal material on at least one of a surface of the liquid crystal multi-panel and a surface of the reinforcing substrate; (b) connecting the liquid crystal multi-panel and the reinforcing substrate via the seal material; (c) injecting a bonding material into a spacing formed by the liquid crystal multi-panel, the reinforcing substrate and the seal material; and (d) hardening the bonding material. The described method permits the amount of use of the bonding material required for connecting the liquid crystal multi-panel and the reinforcing substrate to be minimized. As a result, the need of wasting or refining the excessive bonding material can be eliminated, thereby reducing a manufacturing cost.
