Claim:
A display device, comprising: a pair of light transmissive substrates arranged at an interval; a sealing member which is brought into close contact with opposed surfaces of the pair of light transmissive substrates, the sealing member comprising an opening and surrounding a space defined by the pair of light transmissive substrates; an end seal for closing the opening of the sealing member, thereby encapsulating the space to form an encapsulation space; oil filled in the encapsulation space; a spacer, which is arranged in the oil, for maintaining the interval between the pair of light transmissive substrates; a light shielding film formed on one of the pair of light transmissive substrates, the light shielding film comprising an aperture portion; a shutter arranged in the oil; a drive portion arranged in the oil, for mechanically driving the shutter so as to control passage and blocking of light through the aperture portion; and a wall portion formed on at least one of the opposed surfaces of the pair of light transmissive substrates, wherein the spacer, the shutter, and the drive portion are arranged in a display region for displaying an image depending on presence/absence and intensity of the light passing through the aperture portion, wherein the wall portion comprises a part arranged at a position interrupting a shortest path between the opening of the sealing member and the display region, and wherein the wall portion is made of a material forming the spacer, the shutter, and the drive portion.
