性の良い液晶表示パネルが得られる。 Visibility is increased by dividing one liquid crystal display panel into a plurality of regions and filling each region with a different liquid crystal material. Conventionally, the liquid crystal of a liquid crystal display panel is divided by applying a sealant to one electrode substrate of a pair of electrode substrates that make up the liquid crystal display panel by screen printing in a shape that separates each area, and then applying the sealant to the other electrode substrate. Glue them together. Usually, liquid crystal display panels contain particles with a constant diameter (e.g. alumina abrasive) or fibers (e.g. glass fiber) in the sealing material to maintain a constant distance between a pair of electrode substrates, or evenly spread them over the entire surface of the panel. Spray,
By applying a load to the panel in order to improve the adhesion of the sealant and maintain the electrode-substrate spacing to the diameter of particles or fibers, a liquid crystal display panel with good uniformity in the electrode-substrate spacing can be obtained.

なる。 FIG. 1 shows a conventional display panel in which liquid crystals are divided into a plurality of sections, and a is a plan view of the display panel, and b is a sectional view of the display panel. In this case, the sealing width of the sealing portion 3 of the liquid crystal display panel becomes wider than the width of the sealing material applied by screen printing because the sealing material is crushed by applying a load. In practice, the width of the sealant applied to the electrode substrate by screen printing needs to be at least 0.5 mm in order to obtain sufficient division, and the width of the sealant applied to the electrode substrate by screen printing is approximately 1 mm if it collapses due to the load after gluing. Become. In this way, in the case of screen printing, in addition to the seal width becoming thicker, the edge of the seal part becomes irregular and wavy due to the collapse, and the seal width is not constant. In addition, the roundness of the corners of the divided area becomes large due to crushing.
With a printing width of 0.5mm, the corner radius will be approximately 1mm.
