Claim 0:
1. A production method of a backlight plate, comprising:
providing a light-transmitting underlay substrate which comprises a first area and a second area, wherein the light transmission of the first area of the light-transmitting underlay substrate is less than that of the second area of the light-transmitting underlay substrate;
forming a pad on the light-transmitting underlay substrate corresponding to the first area;
coating a layer of photosensitive material on the light-transmitting underlay substrate and the pad to form a reflective layer;
exposing a position of the second area at opposite sides of the light-transmitting underlay substrate that the reflective layer corresponds to; and
developing the reflective layer to form a groove for exposing the pad on the first area that the reflective layer corresponds to.
