A liquid crystal display device including: a liquid crystal display element that includes a liquid crystal layer, and an upper substrate and a lower substrate opposed to each other via the liquid crystal layer, a plurality of liquid crystal display elements being stacked; wherein a condensing direction of a reflected light by directional control in at least one of the liquid crystal display elements is different from a condensing direction of a reflected light by directional control in at least one of another liquid crystal display elements.

Liquid crystal display device

The invention relates to a liquid crystal display element having a liquid crystal enclosed between a pair of substrates and a multi-layer liquid crystal display element utilizing such elements. A liquid crystal display element having improved strength at enclosing portions thereof is provided without any reduction in the throughput of manufacturing steps along with a multi-layer liquid crystal display element utilizing such elements. A liquid crystal display element for blue includes a first substrate having a first through hole formed to extend from one surface to another, a second substrate disposed opposite to the first substrate and having a second through hole formed opposite to the first through hole to extend from one surface to another, the second through hole having an area greater than that of the first through hole, a liquid crystal layer for blue sandwiched between the first and second substrates, and an enclosing material sealing the first and second through holes such that the liquid crystal for blue forming the liquid crystal layer for blue does not leak through the first and second through holes.

A liquid crystal display panelis manufactured by applying a seal agentto at least of a pair of substrates, enclosing the cell region; opposing the pair of substratesat a prescribed gap to define a cell space; depressurizing the interior of the cell spacethrough an openingformed in at least one of the pair of substratesto thereby securely bond the pair of substrateto each other; and injecting a liquid crystal into the cell space. The atmospheric pressure is applied to the pair of substrates, whereby a uniform external pressure is applied, and the glass substrates can be securely bonded to each other in good condition.

Liquid crystal display panel manufacturing method and device

A method of filling a multilayered cell with media. In the method, a multilayered cell having at least two layers, i.e., a first and second layer, is filled with media. The method comprises forming in the first layer a first medium injection region for filling the first layer with a first medium, forming in the second layer a second medium injection region for filling the second layer with a second medium, the second medium injection region corresponding to a region different from the first medium injection region, superposing the first and second layers, forming within the first medium injection region a first through-hole extending through the multilayered cell in the layer-thickness direction, forming within the second medium injection region a second through-hole extending through the multilayered cell in the layer-thickness direction, and injecting the first and second media into the first and second through-holes, respectively, to fill the first and second layers with the first and second media. Thus, a multilayered cell can be easily produced in a shorter time while attaining a reduction in deterioration during production.
