A display device includes a first electrode formed on a first substrate, and a second electrode formed on a second substrate. An electro-optical material is sandwiched between the first and second electrodes. A protective layer has a first section formed over the second substrate, a second section formed over the first substrate, and a third section formed between the first and second sections. The third section conforms to the shape of sides of the electro-optical material, the second electrode, and the second substrate.
