［産業上の利用分野］
本発明は大面積で高精細な液晶表示装置の製造方法に関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a large-area, high-definition liquid crystal display device.
［従来の技術］
近年、液晶表示装置の技術開発に多大な努力が注がれ、
ＣＲＴに匹敵するような画面サイズ、解像度、画質の液
晶表示装置が実現できるようになった。しかし、この液

フトによって階調が取れなくなる。[Prior Art] In recent years, great efforts have been made in the technological development of liquid crystal display devices.
It has become possible to realize liquid crystal display devices with screen size, resolution, and image quality comparable to CRTs. However, there are still some issues to be solved before this liquid crystal display device can be produced industrially and efficiently. One of these is the issue of gap control. Gap unevenness in liquid crystal display devices has a large effect on display quality. For example, in the case of a TN type, if the gap becomes non-uniform, a portion of the screen may become discolored due to the effect of retardation, or the gradation cannot be obtained due to a shift in the writing voltage.
この効果はＳＴＮ型などのようにツイスト角度が大きい
液晶表示装置はど顕著になる。また画面サイズが大きい
ほどギャップの均一化が難しく、高精細になるほどギャ
ップむらによるコントラストの低下が著しくなる。This effect becomes more noticeable in liquid crystal display devices with a large twist angle, such as the STN type. Furthermore, the larger the screen size, the more difficult it is to make the gaps uniform, and the higher the resolution, the more significant the reduction in contrast due to uneven gaps becomes.
ところで従来の液晶表示装置のギャップ制御技術は、第
３図に示すように、２枚の平面基板の中間にグラスファ
イバやミクロパールからなるスペーサを散布し、平面基
板の周辺をスペーサの混入したシール剤で接着固定する
ことにより、液晶層の厚みをコントロールしていた。By the way, conventional gap control technology for liquid crystal display devices, as shown in Figure 3, involves scattering spacers made of glass fiber or micro pearls between two flat substrates, and sealing the periphery of the flat substrates with the spacers mixed in. The thickness of the liquid crystal layer was controlled by adhesively fixing it with an adhesive.
［発明が解決しようとする課Ｍ］
しかし、前述の従来技術の場合、次に列記するような重
要な課題を有している。すなわち、（１）平面基板の周
辺部のみにシール剤を形成して接着するため、平面基板
の熱膨張率の相違によって平面基板の中央部でギャップ
の膨らみが生じ、液晶を封入した後において、周辺部と
中央部でギャップのむらを生じる。[Problem M to be Solved by the Invention] However, the above-mentioned prior art has important problems as listed below. In other words, (1) since a sealant is formed and bonded only to the periphery of the flat substrate, a gap bulges in the center of the flat substrate due to the difference in the coefficient of thermal expansion of the flat substrate, and after the liquid crystal is sealed, Gap unevenness occurs between the periphery and the center.
（２）前記の中央部の膨らみ部分のスペーサが、封入時
の液晶の流動力によって押し流され、部分的にスペーサ
の密度が変化し、その結果、ギャップのむらが生じる。(2) The spacer in the bulge at the center is swept away by the fluidity of the liquid crystal during sealing, and the density of the spacer partially changes, resulting in uneven gaps.
（３）平面基板の面積を大きくして、大画面の液晶表示
装置を形成する場合、通常存在する平面基板の表面のう
ねりによってギャップのむらが生じる。(3) When the area of a flat substrate is increased to form a large-screen liquid crystal display device, unevenness in the gap occurs due to the undulations of the surface of the flat substrate that normally exist.
などである。etc.

A method for manufacturing a liquid crystal display device according to the present invention will be explained with reference to FIG. FIG. 3A is a schematic cross-sectional view after forming horizontal electrodes 202 on the surface of a first flat substrate 201.

This is a schematic cross-sectional view after forming a liquid crystal alignment film 203 after the horizontal electrode forming step described above.

The process of forming the spacer 204 is as follows. First, a photosensitive polyimide (for example, Ube Industries layer PI-41
0). Next, only the portion to be left as a spacer is formed by exposure and development under predetermined conditions. Finally, the polyimide is cured under predetermined conditions to complete the process. The spacer is preferably formed at a location within the screen that does not interfere with display, such as at the intersection of the gap between adjacent horizontal electrodes and the gap between adjacent vertical electrodes.

程である。The material of the spacer is not limited to polyimide, and resists, other organic materials, or inorganic insulating materials such as glass can be used. Note that a material such as polyimide that has good adhesion to the liquid crystal alignment film or substrate material and has mechanical strength is more preferable. The rubbing process is a process of aligning the surface of the liquid crystal alignment 1I 203 by a rotational rubbing method or the like.

法以外では、スキージ法などが適する。The same figure (d) shows the adhesive body 205 following the above-mentioned rubbing process.
FIG. 2 is a schematic cross-sectional view after formation. Adhesive body 2.5 is one in which adhesive is applied only to the top of the spacer by roll coating. It is important that the thickness of the adhesive 205 is smaller than the height of the spacer so that the adhesive does not spread to the display area of the upper or lower substrate when the adhesive is formed or when the upper substrate is attached. . In forming an adhesive body by the roll coating method, it is possible to form an adhesive body that satisfies the above-mentioned conditions by making the thickness of the adhesive applied to the roll smaller than the height of the spacer. However, if the diameter of the roll is small, there is a risk that the adhesive will come into contact with the display portion of the first flat substrate, so it is necessary to consider the spacer spacing and the diameter of the roll. Other than the roll coating method, a squeegee method is suitable.
第１図に示した液晶表示装置は、第二図（ａ）〜（ｄ）
に沿って製造された下基板と上基板をはりあわせたのち
、その液晶セル内に液晶を封入して完成される。The liquid crystal display device shown in FIG. 1 is shown in FIGS.
After bonding together the lower and upper substrates manufactured along the lines, liquid crystal is sealed in the liquid crystal cell to complete the process.
このようにして製造された液晶表示装置は、表示面積が

、上基板と下基板がスペーサの高さで決まるギャップを

である。The liquid crystal display device manufactured in this manner has a display area of 1 inch diagonally, an STN type, a gap unevenness of 5.8 μm±0.1 μm, and a contrast of 1:15.
The results were good. This reflects the fact that at each spacer, the upper and lower substrates are adhesively fixed while maintaining the gap determined by the height of the spacer, so the gap is uniform throughout the liquid crystal cell. .
