Abstract
A field-emission-typed backlight source structure for liquid crystal panel includes a cathode plate and an anode plate. The cathode plate is connected correspondingly to the anode plate. The cathode plate has a cathode substrate, on which a cathode unit is arranged. The cathode unit is shown as comb-shaped structure and further includes a cathode electrode layer and a gate electrode layer, both of which are coplanar on the cathode substrate, and at an intercrossing position with respect to both which an insulating layer is vertically overlapped to separate two layers. The anode plate further includes an anode unit, which is corresponded to the cathode unit, by the comb-shaped structure of which a matrix area is formed, whereby a luminance contrast is independently provided to the corresponding liquid crystal panel area.
