点もあつた。 However, in the conventional liquid crystal display cell, the side edges of the upper electrode substrate 1 are connected to electrode terminals 6, 6 connected to electrodes on the circuit board via interconnectors.
, the ratio of the display area (the area of the liquid crystal enclosure surrounded by the spacers 5) to the area of the entire cell (the area of the upper electrode substrate 1) is small, and therefore the required display area is small. The cell is too large compared to the cell, and the upper electrode substrate 1 must be made thick in order to provide sufficient mechanical strength to the edge of the substrate where the electrode terminals 6, 6 are arranged. It also had the drawback that it was not possible to make it thinner. In addition, as a manufacturing method for electro-optical display cells such as electro-optic display cells such as liquid crystal display cells, electrodes for multiple cells are formed on each of two electrode substrate materials, and after bonding both electrode substrate materials, individual There is a manufacturing method called the multi-manufacturing method that separates cells into cells (described in detail in the specification and drawings of Japanese Patent Application No. 53-76263), but conventional cells with the above structure have upper and lower parts. Since the sizes of the electrode substrates are different, when manufacturing using the multi-method described above, there was also a drawback that the work of separating the cells into individual cells was troublesome.

The display cell main body 21 is placed between the holding members 20a and 20b with the side to be vapor-deposited facing downward, placed on the vapor deposition mask plate 18, and metal such as chromium is vapor-deposited from below. In this case, since the exposed portions of each display cell body 21 are only the side edges and side surfaces of the lower surface, the vapor-deposited metal layer 1 extending from the lead terminal portions 13a, 13a on the lower surface of the upper electrode substrate 11 to the side surfaces of the substrate is formed in one vapor deposition process.

By eliminating the electrode terminal arrangement part from 1 and making the lower electrode substrate 12 approximately the same size as the upper electrode substrate 11, the spacer 15 is moved to the position where the electrode terminal was formed in the conventional cell. Therefore, with this liquid crystal display cell, the ratio of the display area to the total cell area can be increased compared to the conventional liquid crystal display cell, so when the cell size is the same as the conventional cell, can increase the size of displayed characters, numbers, symbols, etc., or increase the amount of displayed characters, numbers, symbols, etc.
Furthermore, if the display area is the same as that of a conventional cell, the area of the entire cell can be reduced and the size of the cell can be reduced. Furthermore, in this liquid crystal display cell, the electrode terminals 17a, 17a, which are connected to the electrodes on the circuit board via the interconnector, are formed on the lower side edge of the cell, so that the side edge of the conventional upper electrode substrate Unlike cells in which electrode terminals are formed on the lower surface, there is no need to make the upper electrode substrate thicker, and therefore, the upper and lower electrode substrates 11 and 12 can be made thinner, so that the cell can be made thinner.

Since it is an externally exposed area, it can be manufactured using the multi-method described above, and in this case, when separating individual cells, it is possible to cut once from one side instead of cutting from both the top and bottom as in the conventional method. Furthermore, even if the lead terminal portions 3a are led out to both side edges, the electrode terminals can be led out to the bottom surface of the liquid crystal display cell with just two metal vapor deposition steps and conductive paste printing. Therefore, manufacturing is extremely easy. Furthermore, the electrode terminals are led out at the same time in a plurality of cells, and mass productivity can be improved.

はかることも出来る。 As detailed above, in the method of manufacturing an electro-optical display cell of the present invention, the pair of upper and lower electrode substrates have approximately the same shape and the same size, and the outer ends of the lead terminal portions formed on the lower side edges of the upper electrode substrate are After manufacturing a display cell body that is exposed to the outside of the spacer, the side and lower side edges of the lead terminal formation side of this display cell body and other similarly manufactured display cell bodies are exposed to the metal vapor deposition source. Mask evaporation is performed by arranging the evaporation metal sources in close contact with each other while facing each other at a predetermined angle with respect to the evaporation metal source, and simultaneously performs mask evaporation on the lower surface on which the lead terminal portion of the upper electrode substrate is formed for a plurality of display cell bodies. A first vapor deposited metal layer extending from the side edge to the side surface of the electrode substrate and a second vapor deposited metal layer extending from the side surface of the lower electrode substrate to the lower surface side edge of the electrode substrate are formed, and then a display cell is formed. The first part on the side of the main body.
Since a conductive paste or a low-melting point metal is applied to electrically conduct the vapor-deposited metal layer and the second vapor-deposited metal layer, the lead terminal portion can be reliably led to the lower side edge of the lower electrode substrate. In addition, if the lead terminal part is led out to one side edge of the display cell body, metal vapor deposition and conductive paste or low melting point metal deposition are carried out once, and even if it is led out to both sides, metal vapor deposition and conductive paste or low melting point metal are applied. Therefore, it is possible to easily manufacture a thin electro-optic display cell in which the pair of upper and lower electrode substrates have substantially the same shape and size, have a large effective display area, and are thin. Moreover, the present invention can form the first and second vapor-deposited metal layers by arranging a plurality of display cell bodies at a predetermined angle with respect to the metal vapor deposition source, and forming the first and second vapor-deposited metal layers on the lower surface of the adjacent display cell body. Since the vapor deposition area is restricted, mass production can be achieved, and at the same time, the mask pattern of the vapor deposition mask plate can be a simple pattern in which slits corresponding to the lead terminals are formed over the entire length. Furthermore, according to the present invention, a technique for manufacturing a plurality of display cell bodies at once and a technique for simultaneously applying conductive paste, etc. to the side surfaces of a display cell body can be established immediately. Therefore, by using these technologies together, it is possible to further increase mass production.
