Narrative:
I approved air carrier X the LAXX6 departure from runway 24L on a H210 vector departure for local 2. Moments after LC2 called me and coordinated the H210 departure; I launched the Loop4 (CRJ7) departure from runway 25R. As air carrier X was turning 210 degrees in front of the departing CRJ7 I shipped him (CRJ7) without issuing traffic. Although the course divergence was established; and I called the departure sector to advise the radar controller to issue traffic; I should have issued the traffic myself. When I inquired with the radar departure controller if everything was O.K; he said 'yeah' indicating to me that pilots did not complain. My assist was observing all this at the time. Recommendation; use of the placard (visual que) I removed the placard as soon as the other controller told me that the cross-over traffic rolled. In fact; the aircraft did not roll for at least a few seconds; and by removing the placard; I misjudged the distance requirement. Thus; delay removing the visual que. Furthermore; when it appears that it's going to get close enough; then issue traffic.
