FLEXIBLE DISPLAY DEVICE AND METHOD FOR MANUFACTURING FLEXIBLE DISPLAY DEVICE
First Claim
1. A flexible display device, comprising:
- a display panel having flexibility;
a circuit board having flexibility;
a circuit part disposed on the circuit board, the circuit part having rigidity; and
a housing accommodating the circuit board and supporting the display panel above the circuit board, the housing having flexibility, wherein,the display panel, the circuit board, and the housing have flexibility at least along a first direction which is perpendicular to the plane of the display panel;
the housing internally has an upper face and a bottom face, the circuit board being disposed on the bottom face of the housing; and
a length 2a of the circuit part along a second direction which is parallel to the plane of the display panel, a thickness b of the circuit part along the first direction, a distance d between the bottom face and the upper face of the housing or between the bottom face and a lower face of the display panel, and a radius of curvature r of the bottom face of the housing when the housing is curved to a maximum extent along the first direction satisfy the relationship;

Abstract
A flexible display device (100) according to the present invention includes a display panel (10), a circuit board (30), a circuit part (32), and a housing (20). The display panel, the circuit board, and the housing have flexibility at least along a first direction which is perpendicular to the plane of the display panel. A length 2a of the circuit part along a second direction which is parallel to the plane of the display panel, a thickness b of the circuit part along the first direction, a distance d between the bottom face and the upper face of the housing or between the bottom face of the housing and a lower face of the display panel, and a radius of curvature r of the bottom face of the housing when the housing is curved to a maximum extent along the first direction satisfy the relationship a≦[d2−b2+2·r·(d−b)](1/2). According to the present invention, a highly flexible electronic device or display device can be provided by using circuit parts of appropriate sizes, without unnecessarily increasing the device thickness.
