った。Liquid crystal display panels such as STN and TPT usually have a black matrix for blocking light leaking from areas other than the pixel area in order to improve the contrast of conventional displays. However, liquid crystal display panels use spacers within pixels to control the cell thickness, and this prevents the light passing through the spacers from being switched by the liquid crystal (or becoming leakage light). There was a problem of weakening the light shielding effect of the black matrix.

法は知られていない。In order to solve the aforementioned problem of reduced display contrast due to leaked light, some proposals have been made to improve contrast by lowering the density of spacers scattered on the panel, but this method does not require uniform cell thickness over a large area. There is a problem that it becomes difficult to realize. Therefore, attempts have been made to scatter spacers in areas other than the pixel area, but at present it is difficult to achieve good reproducibility and to disperse spacers in areas other than the pixel area, and there are no effective methods. unknown.

(e.g., heat-resistant resin such as), spacers are dry-dispersed on a substrate (e.g., glass, plastic, etc.) having such a black matrix, then infrared rays are irradiated, and then a dry gas such as dry air is blown or blown onto the substrate. This reduces the spacer distribution density in the pixel area by removing the spacers in the pixel area that have weak adhesion.The spacers used in the past (for example, synthetic resin particles with a particle size on the micron order) can be used as they are.

ラストの低下を少なくする。However, as shown in FIG. 2, the inventors have found that the adhesion of the spacers increases when heat is applied to the substrate after the spacers are spread. The present invention has focused on this point, and uses a layered structure of gold-black or gold-black and other materials with extremely high infrared absorption efficiency for the black matrix, and irradiates the black matrix with infrared rays after dry-spreading spacers. The adhesion of the spacer in the black matrix area is improved by creating a temperature difference between the spacer and the pixel area, and then dry air is blown to blow off the spacer in the pixel area, where the adhesion is weak, and the spacer is dispersed in the pixel area. Decrease in contrast due to spacers in the pixel area is reduced by reducing the density.

Gold was deposited in an atmosphere of 0 I Torr and formed by a lift-off method using a resist. The thickness of the gold-black matrix was 2 μm (this thickness is typically 1-3 μm). After dry spraying spacer 4, 70
Place the substrate 1 on a hot plate 5 heated to °C,
30 infrared rays with an intensity of 100+wW/d from infrared source 6
Irradiated for minutes. The gold-black matrix 2 has a higher infrared absorption efficiency than other parts, and therefore, the temperature of the matrix 2 becomes about 30° C. higher than the temperature of the pixel part 7 due to infrared irradiation. The adhesion of the spacer 4 used in this example increases rapidly at about 90°C, so by heating the substrate 1 to about 70°C with the hot plate 5 in advance, the pixel part 7 and the black matrix part 2 can be bonded together. Since the difference in the adhesion strength of the spacer 4 can be increased, the hot plate 5
It is necessary to preheat it to 70°C. In addition,
If a mask 8 used in so-called photolithography is used to irradiate infrared rays only onto black matrix 2 so that infrared rays are not irradiated onto pixel portion 7, the difference in adhesion between spacers 2 will further increase. After that, as shown in FIG. 1(B), for example, dry air 9 is
By blowing away the spacers 4 with low adhesion in the pixel part 7 by irradiating them with a pressure of about kg/c-d from a distance of, for example, 50 cII+, the density of the spacers 4 on the black matrix 2 can be made higher than that in the pixel part 7. Under the above conditions, the density of the spacers 4 in the pixel section 7 was approximately 40% of the density of the spacers 4 on the black matrix 2 (counted with a microscope). This ratio varies depending on the type of alignment film (e.g. Although it depends on factors such as polyimide, PVA (polyvinyl alcohol), SiO obliquely evaporated film, etc.), infrared intensity, and even the hot plate temperature, the most influential factor is the hot plate temperature.
C, the density of the spacers 4 in the pixel portion 7 could be made 50% or less of the density on the black matrix 2.

From the results shown in FIG. 2, it is clear that the adhesion of the spacer particles to the alignment film increases at temperatures above 90° C. in the dry case.

法。[Claims] 1. In a liquid crystal panel having a black matrix, the black matrix is formed of a laminated structure of gold-black or gold-black and other materials, and the density of spacers on the black matrix is adjusted to a pixel area. A liquid crystal panel comprising a substrate having a higher scattering density than other parts including the substrate. 2. Spread a predetermined amount of spacers by a dry method onto a substrate having a black matrix consisting of a laminated structure of gold-black or gold-black and other materials, and then irradiate the substrate with infrared rays to increase the temperature of the black matrix portion. A liquid crystal panel characterized in that the substrate is manufactured by blowing dry gas under a raised state to remove spacers existing in areas other than the black matrix area and increase the density of spacer dispersion in the black matrix area. Production method.
