Abstract: A light guide plate having a pattern to minimize generation of a dark zone and a backlight unit including the same are disclosed. The light guide plate includes an intaglio pattern consisting of recesses formed in a surface opposite to a light emitting surface thereof to have a cross section having major-axis and minor-axis diameters and depth, the recesses being spaced apart from one another in first and second directions by first and second distances respectively. The density of the intaglio pattern is directly proportional to the major-axis and minor-axis diameters and depth, and is inversely proportional to the first and second distances. The intaglio pattern has the minimum density in a first region adjacent to a light source, and the maximum density in a second region that is the maximum distance from the light source. A density ratio of the maximum density to the minimum density is 900.

Abstract: Disclosed herein is a funnel for slim cathode ray tubes. The funnel is constructed such that the deflection angle of an electron beam is 120 degrees or more. On the assumption that, at a top of round (TOR) part located between a body and a yoke part, the thickness of each long side (x-axis) is Tx, the thickness of each short side (y-axis) is Ty, and the thickness of each diagonal part is Td, the following inequality is satisfied: Td>Tx>Ty. The TOR part has a horizontal inner curvature, a horizontal outer curvature, and a vertical outer curvature, which are convex toward the outside of the funnel, and a vertical inner curvature, which is convex toward the inside of the funnel.
