Abstract

Disclosed are folding type display apparatuses. The folding type display apparatus comprises a flexible display section, and a plurality of housings, which includes a first housing having a space formed therein, and second and third housings bendably connected to both ends of the first housing. The display section is fixed to the second and third housings, and in a closed state of the second and third housings, a folding portion of the display section is housed in the space formed by the first housing, while in an open state of the second and third housings away from each other, the display section becomes flat, and the first housing functions as a leg protruding from flat surfaces of the second and third housings, so that the second and third housings are fixed to each other and the folding portion of the display section is supported, by a holding member for connecting these housings.

First claim

What is claimed is:

1. A folding type display apparatus, comprising:
a sheet-shaped display section having flexibility; and
a plurality of housings which hold the sheet-shaped display section,
wherein the plurality of housings include a first housing which has a cross section of a channel shape with a space formed therein, and a plate-shaped second housing and a plate-shaped third housing which are bendably connected to both ends of the first housing in a direction being separated from each other,
the display apparatus further comprises a holding member which is held in the second and/or the third housing,
the sheet-shaped display section is fixed to the second housing and the third housing so as to be folded on a side of the first housing,
in a closed state of the second housing and the third housing, a folding portion of the display section is housed in the space formed by the first housing,
in an open state of the second housing and the third housing away from each other to form the flat display section, the first housing functions as a leg which protrudes from flat surfaces of the second housing and the third housing to a back side,
the holding member connects the second housing and the third housing, fixes the second housing and the third housing to each other, and supports the folding portion of the display section,
the display section is an organic EL display in which a switching element and an organic EL element are formed in a matrix shape between two flexible substrates, and
the two flexible substrates include a laminate of an inorganic film and an organic film, respectively.

2. The folding type display apparatus according to claim 1 ,
wherein the two flexible substrates include a plurality of the laminates respectively, and the inorganic films and the organic films are alternately laminated in the plurality of laminates.
