Display device having a structure to prevent damage to a bent portion of a flexible display
View Patent ↗A flexible display includes a display region and a peripheral region. A first reinforcement film is located on the display region of the flexible display and a second reinforcement film is located on the peripheral region of the flexible display. A semiconductor circuit chip is located on the peripheral region and a flexible board is located on the peripheral region. A side end portion of the first reinforcement film is in contact with a first side end portion of the second reinforcement film and a second side end portion of the second reinforcement film is in contact with one side of the semiconductor circuit chip. A third side end portion of the second reinforcement film is in contact with another side of the semiconductor circuit chip and the second reinforcement film is continuously formed from the first side end portion to the second side end portion.
1. A display device comprising:
a flexible display including a display region and a peripheral region arranged in a length direction, the flexible display being bent in the peripheral region around an axis extending in a width direction orthogonal to the length direction, the flexible display being provided with a light-emitting element layer in the display region; and
a spacer disposed inside a bend of the flexible display and including both end portions on both sides in the width direction, the spacer including a guide surface regulating the bend,
a first reinforcement film on the display region of the flexible display;
a second reinforcement film on the peripheral region of the flexible display;
a semiconductor circuit chip on the peripheral region; and
a flexible board on the peripheral region, wherein
the both end portions of the spacer project from the flexible display in the width direction,
a side end portion of the first reinforcement film is in contact with a first side end portion of the second reinforcement film,
a second side end portion of the second reinforcement film is in contact with one side of the semiconductor circuit chip,
a third side end portion of the second reinforcement film is in contact with another side of the semiconductor circuit chip,
the second reinforcement film is continuously formed from the first side end portion to the second side end portion, and
the first reinforcement film, the first side end portion, the second side end portion, the semiconductor circuit chip, the third side end portion, and the flexible board are arranged in this order along a surface of the flexible display.
2. The display device according to claim 1 , wherein the spacer includes a core layer and a surface layer made of a material softer than the core layer and provided on an outer surface of the core layer.
3. The display device according to claim 1 , further comprising:
a third reinforcement film being opposite to the first reinforcement film via the flexible display,
a fourth reinforcement film being opposite to the semiconductor circuit chip via the flexible display, and
an adhesive material adhering between the third reinforcement film and the fourth reinforcement film.
