Abstract
According to one embodiment, a display device includes a first substrate including a first insulative substrate, an outer peripheral wiring formed above the first insulative substrate, an insulation film disposed on the outer peripheral wiring, a pixel electrode formed on the insulation film in an active area for displaying an image, and a first bank formed in a line shape on the insulation film in a peripheral area surrounding the active area, a second substrate including at least a second insulative substrate, and a sealant which is provided in a manner to envelop the first bank, and which attaches the first substrate and the second substrate.
Claims9
A display device comprising:
- a first substrate including a first insulative substrate, an outer peripheral wiring formed above the first insulative substrate, an insulation film disposed on the outer peripheral wiring, a pixel electrode formed on the insulation film in an active area for displaying an image, and a first bank having a wall shape on the insulation film in a peripheral area surrounding the active area;
- a second substrate including at least a second insulative substrate;
- and
- a sealant which is provided in a manner to envelop the first bank, and which attaches the first substrate and the second substrate ,
- wherein the first bank is spaced apart from the second substrate by the sealant,
- the second substrate further includes a second bank which has a wall shape, is formed in the peripheral area and is enveloped in the sealant, and
- the second bank is spaced apart from the first substrate by the sealant.
A manufacturing method of a display device, comprising:
- preparing a first substrate configured such that an outer peripheral wiring is formed above a first insulative substrate, an insulation film is disposed on the outer peripheral wiring, a pixel electrode is formed on the insulation film in an active area for displaying an image, and a first bank having a wall shape is formed on the insulation film in a peripheral area surrounding the active area;
- and
- attaching the first substrate and a second substrate including at least a second insulative substrate, by a sealant which is provided in a manner to envelop the first bank,
- forming a second bank having a wall shape in the peripheral area below the second insulative substrate,
- forming a first alignment film, which covers the pixel electrode and is discontinuous at a side surface of the first bank, by forming an alignment film material on the active area and the peripheral area of the first substrate, and
- forming a second alignment film, which is opposed to the first alignment film and is discontinuous at a side surface of the second bank, on that side of the second substrate, which faces the first substrate.
