During a taxi for a gate return to Gate XX in LAX we encroached into the boundary of Taxiway B-7. Ground Control instructed us to hold short of B-7 Taxiway but there is no signage indicating the boundary of the taxiway when proceeding eastbound because it is an exit for aircraft landing west on Runway 25R. Recommend using clearly marked taxiways with signage for aircraft proceeding eastbound. For example in this case; Taxiway C-10. There was no conflict with other aircraft or vehicles. Another aircraft used Taxiway B-7 to exit Runway 25R while we were stopped and we followed them into the ramp.
Air carrier Captain reported a taxiway incursion in LAX due to lack of signage indicating where the assigned taxiway starts.
