A display device which is mounted for use on a face of a user, the display device comprising: a display panel (14L, 14R) which is disposed in front of eyes of the user and on which an image to be visually recognized by the user is projected; a connecting portion to which a plate-like member disposed between the eyes of the user and the display panel is connected; a slide portion (32L, 32R) configured to fix the plate-like member between the eyes of the user and the display panel by being disposed in a predetermined initial position and to be slidable in a predetermined direction from the initial position; and a pressing portion configured to press the slide portion (32L, 32R) in a direction which is parallel to the surface of the display panel, wherein the slide portion is pressed by the pressing portion from a position after sliding to the initial position, wherein the slide portion (32L, 32R) fixes the plate-like member connected to the connecting portion by inserting the plate-like member between the slide portion (32L, 32R) and the connecting portion, and wherein the slide portion includes a fixing portion configured to fix the plate-like member by being disposed in the initial position, and an inclined face which has an acute angle of elevation with respect to the fixing portion in an opposite direction to a direction in which the connecting portion exists, wherein the inclined face is configured to be pushed by a projection portion of the plate-like member as the plate-like member inserted in the connecting portion moves in a direction towards the display panel as the surface of the plate-like member is moved to become parallel to the surface of the display panel, thereby causing the slide portion to slide in the predetermined direction from the initial position. a display panel (14L, 14R) which is disposed in front of eyes of the user and on which an image to be visually recognized by the user is projected; a connecting portion to which a plate-like member disposed between the eyes of the user and the display panel is connected; a slide portion (32L, 32R) configured to fix the plate-like member between the eyes of the user and the display panel by being disposed in a predetermined initial position and to be slidable in a predetermined direction from the initial position; and a pressing portion configured to press the slide portion (32L, 32R) in a direction which is parallel to the surface of the display panel, wherein the slide portion is pressed by the pressing portion from a position after sliding to the initial position, wherein the slide portion (32L, 32R) fixes the plate-like member connected to the connecting portion by inserting the plate-like member between the slide portion (32L, 32R) and the connecting portion, and wherein the slide portion includes a fixing portion configured to fix the plate-like member by being disposed in the initial position, and an inclined face which has an acute angle of elevation with respect to the fixing portion in an opposite direction to a direction in which the connecting portion exists, wherein the inclined face is configured to be pushed by a projection portion of the plate-like member as the plate-like member inserted in the connecting portion moves in a direction towards the display panel as the surface of the plate-like member is moved to become parallel to the surface of the display panel, thereby causing the slide portion to slide in the predetermined direction from the initial position.
