A forward-facing vision system for a vehicle includes a forward-facing camera disposed in a windshield electronics module attached at a windshield of the vehicle and viewing through the windshield. A control includes a processor that, responsive to processing of captured image data, detects taillights of leading vehicles during nighttime conditions and, responsive to processing of captured image data, detects lane markers on a road being traveled by the vehicle. The control, responsive to lane marker detection and a determination that the vehicle is drifting out of a traffic lane, may control a steering system of the vehicle to mitigate such drifting, with the steering system manually controllable by a driver of the vehicle irrespective of control by the control. The processor, based at least in part on detection of lane markers via processing of captured image data, determines curvature of the road being traveled by the vehicle.

PURPOSE:To obtain the device provided with reflection electrodes having good reflection characteristics by using a mask with which circular shapes having the diameters within the range of specific values are mingled and the adjacent circular shapes are apart at a specific value or above. CONSTITUTION:An org. insulating film 42 is formed over the entire surface on a substrate 31 so as to cover gate bus wirings, source bus wirings and TFTs 40. Projecting parts 42a having a convergent shape and having 3 to 50mum diameter in the sectional shape of the base parts are formed at a height H in the regions of the org. insulating film 42 where the reflection electrodes 38 are formed by being apart the adjacent projecting parts at >=1mum. Contact holes 43 are formed at the part of the drain electrodes 37. The reflection electrodes 38 consisting of aluminum, silver, etc., are formed on the regions of the org. insulating film 42 where the circular projecting parts 42a are formed. The reflection electrodes 38 are connected to drain electrodes 37 in contact holes 43. These rugged parts are formed by using the mask and, therefore, the depth of the recessed parts is constant and the damages by the insulation defect are not given to the elements. Unequal exposing is prevented by being apart the projecting parts 42a at >=1mum.
