Abstract
A backlight assembly and a liquid crystal display device including the backlight assembly are disclosed. In one embodiment, the backlight assembly includes a light guide plate configured to guide light, emitted from a light source, to a liquid crystal display panel and an optical sheet disposed on an upper surface of the light guide plate and configured to diffuse and collimate the light. The backlight assembly further includes a frame configured to support the liquid crystal display panel and the light guide plate and a shielding tape connected to an upper surface of the frame and extending from the frame to one side of the optical sheet.
Claims18
A backlight assembly of a liquid crystal display device comprising:
- a light guide plate configured to guide light, emitted from a light source, to a liquid crystal display panel;
- an optical sheet disposed on an upper surface of the light guide plate and configured to diffuse and collimate the light;
- a frame configured to support the liquid crystal display panel and the light guide plate;
- a shielding tape including a lower surface connected to an upper surface of the frame and extending from the frame to one side of the optical sheet;
- and
- an adhesive attaching a portion of the lower surface of the shielding tape to the frame, wherein the adhesive is not attached to the remaining portion of the lower surface of the shielding tape and wherein the shielding tape does not contact any optical sheet.
A liquid crystal display device comprising:
- a liquid crystal display panel configured to display an image;
- and
- a backlight unit comprising:
- a light guide plate configured to guide light, emitted from a light source, to the liquid crystal display panel;
- an optical sheet disposed on an upper surface of the light guide plate and configured to diffuse and collimate the light;
- a frame configured to support the liquid crystal display panel and the light guide plate;
- a shielding tape connected to an upper surface of the frame and extending from the frame to one side of the optical sheet, wherein the shielding tape has first and second surfaces opposing each other, and wherein the second surface is closer to the liquid crystal display panel than the first surface;
- and
- an adhesive attached to i) only part of the first surface of the shielding tape and ii) the frame, wherein the adhesive is not attached to the remaining part of the first surface of the shielding tape and wherein the shielding tape does not contact any optical sheet.
A liquid crystal display device comprising:
- a liquid crystal display (LCD) panel having a display area and a non-display area, wherein the display area is configured to display an image, and wherein the non-display area does not display an image;
- a light source;
- a light guide plate configured to guide light, emitted from the light source, to the LCD panel;
- an optical sheet disposed on an upper surface of the light guide plate and configured to diffuse and collimate the light;
- a shielding layer located between the optical sheet and LCD panel and configured to at least partially block light output from the optical sheet such that the output light does not reach the non-display area of the LCD panel, wherein the shielding layer comprises first and second surfaces opposing each other, and wherein the second surface contacts the LCD panel;
- a frame configured to support the LCD panel;
- and
- an adhesive interposed between and attached to only part of the first surface of the shielding layer, wherein the adhesive is not attached to the remaining part of the first surface of the shielding layer and wherein the shielding layer does not contact any optical sheet.
