れる。(Prior Art) 7-day display devices, which are driven at low voltage and consume little power, are used as display units in office equipment, automobiles, and the like. A liquid crystal display device uses a liquid crystal panel in which a liquid crystal phase is sealed between a pair of transparent substrates. In this liquid crystal panel, the gap between both transparent substrates is made constant in order to make the thickness of the liquid crystal phase sealed between each transparent substrate constant. The gap between the two transparent substrates is usually set by interposing a large number of spherical spacers with a diameter of about 5 μm between the two transparent substrates.

ネルの生産歩留りが低下するという問題もある。(Problems to be Solved by the Invention) In the liquid crystal panel manufactured in this manner, spacers are provided not only between display pixel regions but also within the display pixel regions. Spacers disposed within the display pixel area have a problem in that they disturb the orientation of the liquid crystal phase near the spacers, or the spacers refract light and cause light scattering, resulting in a significant deterioration in display quality. . In addition, if a large number of spacers concentrate in a display pixel area, light will not be able to pass through the display pixel area at all times, resulting in a display defect.
There is also the problem that it cannot be used as a liquid crystal panel, and as a result, the production yield of liquid crystal panels decreases.
