## Abstract

A display device including a display panel including a display area and a non-display area surrounding the display area; a window disposed above the display panel; a driving circuit chip disposed in the non-display area and mounted on the display panel; and a light-scattering member interposed between the display panel and the window. The light-scattering member overlaps with the driving circuit chip and contains scattering particles.

## Claims

### Claim 1

A display device comprising:
a display panel comprising a display area and a non-display area surrounding the display area;
a window disposed above the display panel;
a driving circuit chip disposed in the non-display area and mounted on the display panel; and
a light-scattering member interposed between the display panel and the window,
wherein:
the light-scattering member overlaps with the driving circuit chip and contains scattering particles; and
the light-scattering member is in direct contact with the driving circuit chip.

### Claim 2 (depends on 1)

The display device of claim 1, further comprising a light-blocking pattern layer disposed on a lower surface of the window and extended along the non-display area.

### Claim 3 (depends on 2)

The display device of claim 2, further comprising an adhesive member interposed between the window and the display panel and overlapping with an entire surface of the display area and a portion of the non-display area.

### Claim 4 (depends on 3)

The display device of claim 3, wherein the adhesive member is an optically clear resin (OCR).

### Claim 5 (depends on 2)

The display device of claim 2, wherein the light-scattering member is in direct contact with the light-blocking pattern layer.

### Claim 6 (depends on 2)

The display device of claim 2, wherein the scattering particles comprise at least one of TiO2, ZrO2, ZnO, CeO2, TaO2, and SiO2.

### Claim 7 (depends on 6)

The display device of claim 6, wherein a size of the scattering particles ranges from 150 to 200 nm.

### Claim 8 (depends on 1)

The display device of claim 1, wherein the light-scattering member further comprises a binder layer in which the scattering particles are dispersed.

### Claim 9 (depends on 8)

The display device of claim 8, wherein a content of the scattering particles ranges from 0.1% to 20%.

### Claim 10 (depends on 8)

The display device of claim 8, wherein the binder layer comprises an ultraviolet curing agent.

### Claim 11 (depends on 10)

The display device of claim 10, wherein the binder layer is an epoxy resin or an acrylic resin.

### Claim 12

A display device comprising:
a display panel comprising a display area and a non-display area surrounding the display area;
a window disposed above the display panel;
a driving circuit chip disposed in the non-display area and mounted on the display panel; and
a light-scattering member interposed between the display panel and the window,
wherein:
the light-scattering member overlaps with the driving circuit chip and contains scattering particles; and
a width of the light-scattering member is less than a width of the driving circuit chip.

### Claim 13

A display device-comprising:
a display panel comprising a display area and a non-display area surrounding the display area;
a window disposed above the display panel;
a driving circuit chip disposed in the non-display area and mounted on the display panel;
a light-scattering member interposed between the display panel and the window; and
a flexible circuit board disposed in the non-display area and disposed more to the outside than the driving circuit chip,
wherein:
the light-scattering member overlaps with the driving circuit chip and contains scattering particles; and
the light-scattering member does not overlap with the flexible circuit board.

### Claim 14 (depends on 1)

The display device of claim 1, comprising a flexible circuit board disposed in the non-display area and disposed more to the outside than the driving circuit chip,
wherein the light-scattering member overlaps with the flexible circuit board.

### Claim 15 (depends on 13)

The display device of claim 13, wherein the scattering particles comprise at least one of TiO2, ZrO2, ZnO, CeO2, TaO2, and SiO2.

### Claim 16 (depends on 15)

The display device of claim 15, wherein a size of the scattering particles ranges from 150 to 200 nm.

### Claim 17 (depends on 13)

The display device of claim 13, wherein a width of the light-scattering member is greater than a width of the driving circuit chip.

### Claim 18 (depends on 13)

The display device of claim 13, further comprising an adhesive member interposed between the window and the display panel, wherein the adhesive member is an optically clear resin (OCR).
