    • A backlight unit and a display module employing the backlight unit. The backlight unit of a display apparatus displaying an image, the backlight unit including: a light guide panel guiding light to the display apparatus; a circuit board having a plurality of light source devices mounted thereon and which is formed at a side of the light guide panel; a light leakage preventing portion including: an interval removing portion formed in the light guide panel, and an adhesive portion attached to the interval removing portion and formed on the circuit board, wherein the light leakage preventing portion is formed in a portion of the circuit board attached to the light guide panel. The light leakage preventing portion is formed in a side portion of a light guide panel. Thus, even when an adhesive portion is not formed in front of a light source device of a circuit board, a height difference between a portion of the circuit board where the adhesive portion is formed and a portion of the circuit board where the adhesive portion is not formed can be compensated, thereby improving brightness of a backlight unit and preventing light from leaking.
    • 背光单元和采用背光单元的显示模块。 显示图像的显示装置的背光单元,所述背光单元包括:向所述显示装置引导光的导光板; 电路板,其具有安装在其上的多个光源装置,并且形成在所述导光板的一侧; 防漏光部分包括:形成在导光板中的间隔去除部分和粘附部分,其安装在间隔去除部分上并形成在电路板上,其中防漏部分形成在电路板的一部分中 连接到导光板。 防漏部分形成在导光板的侧部。 因此,即使在电路基板的光源装置的前方没有形成粘合部的情况下,形成有粘合部的电路基板的一部分与粘合部的电路基部的高度差 可以进行补偿,从而提高背光单元的亮度,防止光的泄漏。
