Japanese Patent JP7363332

B2

To provide an electro-optical device that comprises wiring boards mounted in multiple stages and has good display quality.SOLUTION: An electro-optical device includes: a liquid crystal panel 2; a first wiring board 12 that is connected to a connection area with a first anisotropic conductive film 11 therebetween; and a second wiring board 14 that is connected to the connection area with a second anisotropic conductive film 13 therebetween. From an end 4a, a first panel terminal part 27 including a first panel terminal 29 and a second panel terminal part 28 including a second panel terminal 31 are arranged in this order separated from each other. A first wiring terminal 18 included in a first wiring terminal part 12a being a connection part of the first wiring board 12 is electrically connected to the first panel terminal 29. The second wiring board 14 is arranged overlapping the first wiring board 12. A second wiring terminal 24 included in a second wiring terminal part 14a being a connection part of the second wiring board 14 is electrically connected to the second panel terminal 31. The second panel terminal part 28 includes a detection terminal 32 that is arranged closer to the first panel terminal part 27. The detection terminal 32 is electrically connected to the first panel terminal 29.SELECTED DRAWING: Figure 3
