<P>PROBLEM TO BE SOLVED: To suppress degradation in image quality by birefringence or the like without increasing the cost. <P>SOLUTION: A first region on a semiconductor substrate 3 enclosing a display region is laminated on a second region on a transparent electrode 5 corresponding to the first region with a sealing part 21, while keeping a predetermined gap between the regions. The sealing part 21 has a successively layered structure including a strong adhesive sealing material 22a, a highly flexible sealing material 23 and a strong adhesive sealing material 22b. By using the strong adhesive sealing materials 22a, 22b, moisture resistance on interfaces of the sealing materials with upper and lower substrates is improved. By interposing the highly flexible sealing material 23 between the strong adhesive sealing materials 22a, 22b, physical and chemical bonds between the sealing part 21 and the upper and lower substrates are weakened to decrease birefringence. <P>COPYRIGHT: (C)2012,JPO&INPIT |
