- the light shielding tape 160 was attached onto the overlayer 110 of the liquid crystal panel 110 so as to cover the periphery (parting off part) of the liquid crystal panel 110 which does not substantially contribute to display and operation.
- the first patterning is usually a region where the transparent conductive film is left unetched (a region where the transparent conductive film is solid and there is almost no gap).
- gas penetration is infrequent, but once it has penetrated, it is difficult to be discharged and gas bubbles are likely to be generated. If air bubbles are generated in this area, it is not preferable because the air bubbles cause a clear display failure, for example, when the display content of the display unit 150 is transmitted.
- a hole 14 1 is provided as an opening in the entire first patterned area 130 to facilitate discharge of the gas that has intruded into the liquid crystal layer 100 through the hole 14 1.

- the third patterned area 134 is a surrounding area of the first patterned area 130 and is a parting portion hidden behind the light shielding seal 160. Therefore, the liquid crystal layer 10 9 corresponding to this part is omitted. Even if bubbles are generated, it is likely that this will not cause any major problems. However, since it is adjacent to the first patterned area 130, the third patterned area 1
- the possibility of the gas being accumulated in the first patterned area 130 decreases. Therefore, in the third patterned area 134, as in the first patterned area 130, the pores 1 as a whole are formed.
- Figure 3 (a) shows the third patterned area 1 34 partially enlarged portion 1 42.
- the diameter and the like of the pores 14 3 are the same as in the case of the first polarization region 130.
- the generally visible pixel size ie, the patterned area
- the area made of the transparent electrode material narrower than this is a wiring or the like, and is adjacent to the area without the transparent electrode material in plan. Therefore, the air bubbles generated here can move to the substrate support through the gap of the area made of the transparent electrode material. In general, air bubbles of about 100 m in diameter often cause appearance problems.
- the opening may be provided if the patterned area is larger than a square of approximately 200 m square.
- the display defect causing the appearance problem is approximately 10 0 / im in diameter, it is preferable to make the opening smaller than a square of approximately 100 m square.

- the positions of the pores are arranged so as to completely face each other in the first and second transparent electrode patterns. Since the voltage can not be accurately applied to the liquid crystal layer 10 9 in the portion where the pores are present, it is not possible to perform switching control of the transmission mode and the non-transmission mode of the liquid crystal layer 1 0 9. Therefore, in order to minimize uncontrollable portions, the pores are disposed so as to completely face each other in the first and second transparent electrode patterns 120 and 121.
