Problems solved by technology

like Figure 11 As shown, in this liquid crystal cell, the sealing material 125 on the side of the terminal region T is extended to the line P to be divided.
In this way, when the CF substrate 130 is thin, since the strength of the substrate itself is weak, even if the CF substrate 130 is forcibly torn off, not only the useless substrate W cannot be separated at the normal position (planned dividing line P), but the CF substrate is often broken. 130 broken with useless substrate W

Abstract

A liquid crystal cell (50a) is provided with a TFT substrate (20a); terminal region (T) specified along one side of the TFT substrate (20a); a CF substrate (30a) arranged to face the TFT substrate (20a) so that the terminal region (T) is exposed; a frame-like seal material (25a) having a widely formed seal connecting section (S); a display region (D) specified inside the seal material (25a); and four frame side region specified by the periphery of the display region (D) with the seal material (25a) arranged thereon. The seal material (25a) is arranged by being more spaced apart from an end section of the CF substrate (30a) compared with other three frame side regions and has a seal connecting section (S) in the widest one frame side region among the four frame side regions. Since the sealconnecting section (S) is spaced apart from the end section of the CF substrate (30a), divided failure of the liquid crystal cell (50a) can be suppressed. The liquid crystal cell (50a) can be used, for instance, for a cellular phone.

Description

technical field [0001] The present invention relates to a display unit manufactured by bonding a pair of substrates together with a sealing material, and particularly relates to a liquid crystal cell manufactured by a drop injection method. Background technique [0002] A typical liquid crystal cell has a structure in which a first substrate and a second substrate having different sizes are bonded together with a frame-shaped sealing material. In addition, electrodes for applying a voltage to the liquid crystal layer sandwiched between the first substrate and the second substrate are arranged facing each other on the respective surfaces of the first substrate and the second substrate. [0003] Figure 8 is a plan view of a conventional liquid crystal cell 150a in which a monolithic circuit is formed in a substrate, Figure 9 It is a plan view for explaining the structure of the sealing material 125a of the liquid crystal cell 150a. [0004] Such as Figure 8 and Figure 9...
