    • The present invention generally relates to a backlight unit having improved luminance and uniformity, and a liquid crystal display (LCD) including the backlight unit. A backlight unit according to the invention comprises a light source and a light guide panel having a light receiving portion which receives light emitted from the light source and which has a pattern including a plurality of protrusions. Each of the protrusions has inclined surfaces forming an angle with respect to the tangential direction of the light receiving portion. The inclined surfaces include a first inclined surface relatively close to the center of the light receiving portion and a second inclined surface relatively close to the edge of the light receiving portion. A first inclination angle formed by the first inclined surface with respect to the tangential direction of the light receiving portion is smaller at the edge of the light receiving portion than at the center of the light receiving portion.
    • 本发明一般涉及具有改善的亮度和均匀性的背光单元和包括该背光单元的液晶显示器(LCD)。 根据本发明的背光单元包括光源和导光板,该导光板具有接收从光源发出的光并具有包括多个突起的图案的光接收部分。 每个突起具有相对于光接收部分的切线方向形成一角度的倾斜表面。 倾斜表面包括相对靠近光接收部分的中心的第一倾斜表面和相对靠近光接收部分的边缘的第二倾斜表面。 由第一倾斜面相对于光接收部的切线方向形成的第一倾斜角在光接收部的边缘处比在光接收部的中心处小。
