A display device comprising:
- a front plate including a plurality of display regions having a light-transmitting property and a peripheral region disposed around an outer periphery of the display region;
- and
- a plurality of display panels provided facing the display regions of the front plate, the display panels including a first display panel and a second display panel adjacent to the first display panel,
- wherein
- the front plate includes
- a plurality of alignment marks provided in the peripheral region at positions corresponding to a plurality of display-panel-side alignment marks provided on the display panels;
- and
- a plurality of first marks each having a linear portion extending in a first direction along the outer periphery of the display panel,
- the first marks include a linear mark provided along a side of the display panel, and an L-shaped mark provided on the front plate and corresponding to a corner of the first display panel,
- the alignment marks of the front plate include a common alignment mark provided at a position adjacent to the L-shaped marks and corresponding to two of the display-panel-side alignment marks respectively provided on the first display panel and the second display panel,
- the L-shaped mark overlaps an area of the first display panel, the area being between the common alignment mark and one of the display regions adjacent to the common alignment mark in the first direction, and
