Narrative:
Cleared to taxi via C; B5; B; G; D to runway 19L. Once established on taxiway B; first officer (first officer) advised he was heads down to load final numbers into FMC for takeoff while I was looking for signs marking taxiway G. I passed taxiway G thinking it was B7; but realized my mistake as I could see no further angled taxiways to my right. I stopped the aircraft to obtain an amended clearance from ground control; and was re-cleared to taxi via B; Z; and D. This was my 13th trip into las this month; with most departures previously operating from runway 1R. Prior to gate departure on this flight; I briefed the hot spots and expected runway; but did not brief an expected taxi route as it is unpredictable due to construction. Although I missed the turn; traffic was not a factor and at no time were we near a runway intersection or in danger of incurring on a runway.contributing factors were poor or non-existent markings to indicate taxiway G from taxiway B; and difficulty in reading the 10-9 airport diagram on my ipad due to bright sunlight conditions.
