たその散布方法も防塵策を採り乍ら作業を行うことを要
し、精度及び歩留の上で問題があった。[Prior Art] Conventionally, when manufacturing a liquid crystal display device having a thin cell gap of 1 to 21, a spacer is used to form a gap between two substrates of a liquid crystal cell.
Alumina powder, glass fiber beads, etc. having a size of 1 to 2 strands were used. However, due to the nature of these powder materials, it is difficult to control quantitative dispersion, and the dispersion method also requires dust-proofing measures to be taken during work, which poses problems in terms of accuracy and yield. Ta.
［発明が解決しようとする問題点コ
本発明は、この様な従来例の欠点であるスペーサーの配

It is an object of the present invention to provide a method for manufacturing a substrate with projections for a spacer that can be efficiently reproduced.
［問題点を解決するための手段コ

起つき基板の製造方法である。[Means for solving the problem, that is, the present invention applies a load to a minute portion of the surface of a glass plate used as a substrate of a display device to cause flow deformation to form a groove with a raised periphery. This method of manufacturing a substrate with projections for a spacer is characterized in that the surface of the substrate is undercoated to cover the grooves to form fine projections, and then a transparent electrode is provided.
本発明において、突起の高さは２湊■以下、好ましくは
１〜２鉢ｌが望ましい。In the present invention, the height of the protrusion is preferably 2 cm or less, preferably 1 to 2 liters.
［作用コ
一般に、ガラスは理想的なもろい物質と考えられ、その
破壊も脆性破壊の代表として考えられているか、しかし
実際にはガラスでも塑性変形をする。[Function] Generally, glass is considered to be an ideal brittle material, and its fracture is considered to be a representative example of brittle fracture, but in reality, even glass undergoes plastic deformation.
即ち、先端か尖鋭な硬質材料でガラス表面の微小部分に
集中的に荷重を加えると、塑性流動的変形を行う（マイ
クロプラスティンティ）。In other words, when a concentrated load is applied to a minute portion of the glass surface using a hard material with a sharp tip, plastic flow deformation occurs (microplastination).
ガラス表面に輻及び深さｌ終■以下の微細なきすをつけ
ると、ガラス表面のキズは金属や、樹脂の表面に見られ
るような滑らかな溝であって割目を伴わない。When fine scratches with a radius and depth of less than 1 are made on the glass surface, the scratches on the glass surface are smooth grooves like those found on the surface of metal or resin, without cracks.
該溝の周辺に認められる隆起は溝の中のガラスか塑性流

すしを入れた場合、二つの切りすじが交叉するとき、最
初の切りすしが次の切りすしによって埋められるという
事実からも、この塑性流動的変形の存在の裏付けを認め
ることができる。The ridges observed around the groove are caused by the glass in the groove being pushed laterally by plastic flow. For example, when cutting sushi with a fine width into glass using diamonds or the like, the fact that when the two cutting lines intersect, the first cutting sushi is filled by the next cutting sushi, this plastic fluid deformation We can confirm the existence of

ものである。Therefore, the present invention applies a load to a minute portion of the surface of a glass plate to cause plastic deformation, forms a plurality of grooves with a raised periphery, and covers the grooves with a plurality of grooves with a height of less than 2. By forming a protrusion on the surface, it can play the role of a spacer.
［実施例］ 以下、実施例を示し本発明をさらに具体的に説明する。[Example] Hereinafter, the present invention will be explained in more detail with reference to Examples.
実施例１

で１００ＯＡの厚さに形成した。As shown in FIGS. 1(a) to 1(d), a one-point diamond scriber tip 1 with a conical tip is supported on a jig 2, vertically stood on a glass substrate 3, and the jig is When a load of 100 to 500 g was gently applied to 2, a groove 5 with a depth of about 0.8 mm, a height of the ridge 4 of about 11 zm, and a diameter of about 5 to 10 mm was formed. Using this glass substrate, a 5iOz undercoat film 6 is applied by sputtering.
The coating was applied to a thickness of 00 to 100 OA to form protrusions 7 with a height of 1.0 gm. Further, ITO was formed thereon by sputtering to a thickness of 100 OA.

とができた。When patterning ITO, the protrusions 7 were aligned so that they did not overlap the pattern. When a cell was created by combining the glass substrate with the protrusions thus obtained on its surface and a regular glass substrate and gluing the periphery with adhesive, the protrusions 7 served as spacers to create a cell with a uniform gap. When liquid crystal was injected, a good liquid crystal device was obtained.
