## Abstract

An object is to provide a display apparatus capable of suppressing damage to flexible printed boards. Each flexible printed board (31) is bent so as to be farther from a bezel (21) and thereby protected totally in a peripheral edge direction of a display panel (11). Therefore, contact between the flexible printed board (31) and the bezel (21) can be suppressed. This makes it possible to suppress displacement or twist or the like of the flexible printed board (31) due to contact with the bezel (21). Thus, damage to the flexible printed board (31) attributable to contact between the flexible printed board (31) and the bezel (21) can be suppressed.

## Claims

### Claim 1

A display apparatus comprising:
a display panel;
a front frame body which supports a peripheral edge portion of the display panel from a front of the display panel;
a back frame body which supports the peripheral edge portion of the display panel from a back of the display panel;
a flexible printed board protruded from the peripheral edge portion of the display panel and bent toward the back frame body at a bent portion of the flexible printed board; and
a protective member attached to the back frame body, wherein
the protective member includes:
a sheet portion interposed between the front frame body and the flexible printed board; and
two protruding portions attached to the back frame body, side by side along a peripheral edge direction of the display panel and protruded from one surface of the sheet portion,
the flexible printed board is between the two protruding portions,
a distal end of the flexible printed board is in contact with the sheet portion,
the sheet portion is spaced apart from the flexible printed board at all portions except for the distal end,
each of the front frame body and the back frame body is a seamless body,
a first fitting portion that is a portion of the front frame body and a second fitting portion that is a portion of the back frame body are attached to each other,
a portion of the first fitting portion is opposed to an opposing portion of the back frame body,
a portion of the flexible printed board is located between the portion of the first fitting portion and the opposing portion of the back frame body, and
the portion of the flexible printed board is surrounded by the opposing portion of the back frame body, the sheet portion, and the two protruding portions.

### Claim 2 (depends on 1)

The display apparatus according to claim 1, wherein
the two protruding portions are bonded to the back frame body, and
a bonding region of each of the two protruding portions to the back frame body has an area of at least 4 mm×3 mm.

### Claim 3 (depends on 1)

The display apparatus according to claim 1, wherein
the sheet portion is more flexible than the two protruding portions, and
a protruding length of each of the two protruding portions is larger than a thickness of the sheet portion.

### Claim 4 (depends on 1)

The display apparatus according to claim 1, wherein a fit-in portion into which each of the two protruding portions is to be fitted is provided in the back frame body.

### Claim 5 (depends on 1)

The display apparatus according to claim 1, wherein the sheet portion of the protective member is interposed between the front frame body and, a portion between the bent portion and the distal end of the flexible printed board.

### Claim 6 (depends on 1)

The display apparatus according to claim 1, wherein
an electronic component is mounted on a surface of the flexible printed board facing the back frame body, and
the electronic component and the back frame body are separate from each other.
