In forming the sealing member, a ring-shaped portion that seals the liquid crystal layer inside the sealing member, a first sealing layer and a second sealing layer that face each other to be separated from each other are formed. In the bonding of the first substrate to the second substrate, a junction portion is formed in which the first and second sealing layers are pressed and joined outside the sealing member so as to form the ring-shaped portion.

  • Patent number: 9406808
    Abstract: In a channel protected thin film transistor in which a channel formation region is formed using an oxide semiconductor, an oxide semiconductor layer which is dehydrated or dehydrogenated by a heat treatment is used as an active layer, a crystal region including nanocrystals is included in a superficial portion in the channel formation region, and the rest portion is amorphous or is formed of a mixture of amorphousness/non-crystals and microcrystals, where an amorphous region is dotted with microcrystals. By using an oxide semiconductor layer having such a structure, a change to an n-type caused by entry of moisture or elimination of oxygen to or from the superficial portion and generation of a parasitic channel can be prevented and a contact resistance with a source and drain electrodes can be reduced.
