Abstract
To provide an electro-optical device comprising a thin film having a uniform thickness, which is formed by drying liquid droplets filled in a liquid droplet ejection region surrounded by a partition. An electro-optical device comprises partitions 22 for separating a plurality of regions formed on a substrate 10. Each of the partitions 22 has a lyophilic first partition 43 and a liquid-repellent second partition 44 which is formed on an upper surface portion of the first partition except for a circumferential portion surrounding the region of the first partition 43. The device also comprises a functional layer 45 which is formed on the region surrounded by the partition and includes at least a light emitting layer. The device further comprises a pair of electrodes 41 and 46 with the functional layer interposed therebetween, in which the first partition 43 has the thickness larger than the thickness of the functional layer 45, and a side inclined angle of the first partition 43 is less than the side inclined angle of the second partition 44.
