Abstract
The present invention provides a structure in which a pixel region 13 is surrounded by a first sealing material (having higher viscosity than a second sealing material) 16 including a spacer (filler, minute particles and/or the like) which maintains a gap between the two substrates, filled with a few drops of the transparent second sealing material 17a which is spread in the region; and sealed by using the first sealing material 16 and the second sealing material 17.
