Abstract

The object is to provide a technique capable of preventing, in a display device, bubbles from being trapped between a protective plate or a touch panel and a display panel and occurrence of display inhomogeneity. The display device includes a display panel, a backlight unit, a cushion serving as a support, and a first frame. The first frame includes: an opening through which the backlight unit is seen; a sidewall covering side surfaces of the backlight unit to form the opening; a panel facing portion extending from the sidewall toward the opening side to cover an end portion of the backlight unit; and a protruding portion protruding from the panel facing portion toward the display panel side. The cushion is disposed on the panel facing portion. The protruding portion is thinner than the cushion. A predetermined clearance is created between the tip of the protruding portion and the display panel.

Claims (19)

1. A display device, comprising:

a display panel;

a backlight unit disposed opposite to a display surface of the display panel;

a support supporting the display panel, the support being arranged between the display panel and the backlight unit, the support being made of an elastic material; and

a frame-shaped frame holding a front portion and side portions of the backlight unit,

the frame including (i) an opening through which the backlight unit is seen, (ii) a sidewall covering side surfaces of the backlight unit to form the opening, (iii) a panel facing portion extending from the sidewall toward the opening side to cover an end portion of the backlight unit, and (iv) a protruding portion protruding from the panel facing portion toward the display panel side,

wherein the support is disposed on the panel facing portion,

the support is in direct contact with the display panel,

the protruding portion is thinner than the support, and

a predetermined clearance is created between a tip of the protruding portion and the display panel such that where a thickness of the support is C and a thickness of the protruding portion is X, a relationship C/2≥X is met.

2. The display device according to claim 1 ,

wherein the support is disposed on a periphery of the opening, and

the protruding portion is formed on the sidewall.

3. The display device according to claim 1 ,

wherein the support is disposed on a periphery of the sidewall, and

the protruding portion is formed on a periphery of the opening.

4. The display device according to claim 1 ,

wherein the display panel includes a thin-film transistor substrate, and a counter substrate facing the thin-film transistor substrate, and

the display device further comprises a protective plate attached to a front surface side of the counter substrate.
