A portrait of Krisjanis Barons and a stylised oak-leaf (a see-through register) are superimposed on a motif of traditional Latvian ornaments. On the banknote issued in 2007, there is a vertical translucent band on the left of the portrait, which covers the see-through register and the transparent window above it, with the latter featuring a red semicircle of the Sun on a light background and the letterings "Ls" in four displaced lines on a dark background. There is a silver semicircle of the Sun between the transparent window and the see-through register. Across the top of the banknote, there is the inscription LATVIJAS BANKAS NAUDAS ZIME (money note of the Bank of Latvia). Across the bottom of the banknote, there are the inscriptions SIMT LATU (one hundred lats) in two-coloured print, LATVIJAS BANKA (Bank of Latvia), the facsimile signature of the Governor of the Bank of Latvia, and the serial number of the banknote in black print. On the right side of the banknote, there is a vertical ornamental band composed of the motif of Lielvarde belt and the numeral 100. On the left side of the banknote, there are two relief dots (Braille) in red print arranged diagonally on a white background; on the banknote issued in 2007, there is the serial number in red print on the left of the relief dots, with a watermark incorporated beneath. Below the watermark, there is a horizontal band with a colour changing optical effect and the numeral 100; on the banknote issued in 2007, there is a horizontal band with the numerals 100 in greyish brown print and the numeral 100 in a larger reddish brown print, which changes to greyish green or brown when the banknote is tilted, and acquires a different shade under the impact of heat.
