Liquid crystal display device having a circuit board disposed at a recess of a light guide plate

Claim 2

A liquid crystal display device comprising: a wedge shaped edge light type light guide plate for a backlight, having an inclined major front surface; a back light lamp disposed adjacent to a wide edge surface of said light guide plate; a liquid crystal display panel disposed adjacent to the rear surface of said light guide plate; a circuit board disposed adjacent to said front surface in the thinnest region of said light guide plate without extending along the entire said front surface; a tape carrier connecting said liquid crystal display panel and said circuit board with each other; and an integrated circuit disposed on said tape carrier for driving said liquid crystal panel.

Claim 3

A liquid crystal display according to claim 1, wherein light reflection coatings are disposed on edge surfaces of said light guide plate except for the edge surfaces of said light guide plate for receiving or emitting a light.

Claim 4

A liquid crystal display according to claim 1, wherein a lamp inverter circuit or other circuit board is mounted adjacent said front surface and next to said circuit board without extending to the thickest region of said light guide plate.

Claim 5

A liquid crystal display according to claim 1, wherein said liquid crystal display panel is provided with a tape carrier at two sides thereof, and an L shaped lamp is disposed at the other two sides of said liquid crystal display panel opposed to said two sides with said tape carrier.

Claim 6

A liquid crystal display device comprising: an edge light type light guide plate for a backlight, having a major front surface, a major rear surface and four minor side surfaces, wherein said front surface consist of two inclined surface sections, one of said inclined surface sections being inclined in a direction from said first side surface and the other inclined surface section being inclined in a direction from said second side surface, wherein said first and second side surfaces are adjacent and orthogonal; an L shaped lamp disposed adjacent to said first and second side surfaces; a liquid crystal display panel disposed adjacent to said rear surface of said light guide plate; a circuit board disposed adjacent to said front surface in the thinnest region of said light guide plate without extending along the entire said front surface; a tape carrier disposed adjacent to said third and fourth side surfaces connecting said liquid crystal display panel with said circuit board.

Claim 7

A liquid crystal display device comprising: an edge light type light guide plate for a backlight, having a major front surface, a major rear surface and four minor side surfaces, wherein said front surface consist of two inclined surface sections, one of said inclined surface sections being inclined in a direction from said first side surface and the other inclined surface section being inclined in a direction from said second side surface, wherein said first and second side surfaces are adjacent and orthogonal; an L shaped lamp disposed adjacent to said first and second side surfaces; a liquid crystal display panel disposed adjacent to said rear surface of said light guide plate; a circuit board disposed adjacent to said front surface in the thinnest region of said light guide plate without extending along the entire said front surface; a tape carrier disposed adjacent to said third and fourth side surfaces connecting said liquid crystal display panel with said circuit board.
